assisted in the tests carried out in the laboratory and the
works. A number of determination methods for such investigations
are already known. They are, howeverg inaccurate or too com-
plicated, as for example the method of estimating the boring
suitability according to the critical pressure at which a
cavity is formed on the sample. With this method a greater number
of test pieces is required in order to obtain accurate results.
In order to remove this shortcoming a method was developed,
using conical or step-shaped aamples. The critical pressure is
computed from a Given equation. After the test the bore-hole

obtained which correspond to the dimensions of the sample and
of the bore-hole, In order to find the range of applicability
and the accuracy of the method tosts were made with a number
of steel types. The samples were heated to 12000 for 20 minutes.
The results obtained for the different steel types are given.
It was found that values obtained from control samples of the
step-like and the conical type are comparatively close to each
other. However, the latter Give more precise values than the
first. Among other tests comparative determinations were carried
out according to a method which was developed by the Institute
for Electric Welding imeni Paton AS Ukraine SSR. The method was
found to have a satisfactory aciuracy. Hence it can be applied
as a standard method for this type of determination with highly-
alloyed and alloyed steels. There are 4 figures, 3 tables, and

ABSTRACT: Efforts made in 1956 to produce seamless tubes from high-
alloy steels containing boron EI769 and BI770 gave
negative results but in 1957 after some changes in the
technollogy of smelting the metal, satisfactory results
were obtained although there were no substantial changes

SOV/133-59-1-15/23
The Teebmology of Production of Seamless Tubes from High-alloy Steels
Alloyed with Boron
The main characteristics of the technology of smelting
metal in 1956 and 1957 differed as follows; a) in 1956,
smelting was carried out in a 20-ton arc furnace from a
charge containing 40-4?% of stainless scrap (the remaining-
soft iron and fresh ferroalloys); oxygen 3was used during
melting and oxidising period (500 - 700 m per heat); slag
and metal were deoxidised before the addition of ferro-
chromium and with the addition of ferrotitanium onto the
metal freed from slag 15-20 min before tapping; b) in
1957 smelting was carried out in a 4.5-ton are furnace from
a fresh charge containing from 55 to 78% armco iron and
corresponding ferroalloys without utilisation of scrap and
oxygen; refining under a white slag with the addition of
ferrotitanium. after the removal of slag 8-10 min before
tapping. In both cases the metal was cast in 500-kg ingots.
The quality of tube billets 85 mm in diameter in 1957 was
higher than in 1956. The microstructure of metal in both
cases consisted of austenite with fine intermetallic
inclusions, stretched in the form of lines along the
direction of rolling. Piercing ability of the steels was
Card2/5 tested on conical specimens (Ref 3). The determination of

SOV/133-59-1-15/23

plasticity and structure of stee;s was carried out within
a temperature range 950 - 1 300 C. Both steels were found
to possess a comparatively higg plasticity in the
temperature range 975 - 1 0?5 C (Figures 1 and 2), higher
than for steel lKhl8N9T. However, the plasticity of the
latter steel increases with increasing temperature while
for EI?69 and ??0 it sharply decreases. In hot torsion
tests (Figures 3 and 4) the differences in the plasticity
of the experimental steels was more pronounced. The
resistance to deformation of both steels is simi3w (Figure 4)
but at all temperatures,is higher than for lKhl8NqT steel.
In hot torsion tests the loss of plasticity of the experi-
mental steels was less pronounced than in piercing tests.
In the first case, Inss of plasticity wasoobserved at
1 300 OC and in the second case at 1 250 C. On the basis
of the above investigation the'following piercing'practice
for the industrial conditions was pEoposed: the temperature
of billets before t ge mill 960-980 C, piercing tempera- 0
ture 1 100 1 1200 C. in addition piercing at 1 1.40 - 1 150
Card3/5 and 1 180 1 200 C was tested. Hot rolling of tubes

under industrial conditiona is described in some detail.
The results obtained are given in Table 1. The inspection
of tubes atter pickling indicated that for steel RI769 0the
proposed piercing practice (temperature 1 100 - 1 120 0)
gave the best results. A large-scale rolling of tubes
from this steel yielded 90% of good-quality products.
Rolling of tubes from steel EI770 was tried at four
different temperature ranges (temperature before 0piercing:
920-980- 980-1 000; 1 020-1 040 and 1 040-1 050 C -
Table 25. Optimum resu;ts were obtained at a temperature
before piercing of 950 C. 95%/ of good-quality tubes was
obtained. Mechanical properties of hot-tolled tubes before
and after hardening are given in Wable 3. HardeLing of
tubes was carried out from 1 100 C. The dependence of the
consumption of energy, power and heating-up of the metal
during piercing on the temperature of the metal before
piercing is shown in 1rigure 6. It is concluded that:
1) boron-containing.steels of austenitic class EI?69 and
ZI?70 possess a lowered temperature at the beginning of
incipient melting of grain boundaries; their optimum
Card4/5 plasticity is shifted towards lower temperatures; they

SOV/133-59-1715,/23
The Technology of Production of Seamless Tubes from gh-alloy
St~eels Alloyed with Boron
possess high-resistance to deformation and heat up
intensively during piercing. The resistance to defor-
mation of these steels is higher than of lKhl8N9T steel
which makes their piercing more difficult, particularly
that with increasing temperature their plasticity decreases
(unlike lKhl8N9T steel). The-developed methods of rolling
these~zteeliw Sivo-quality hot-rolled tubes from BI769
steel without.repairs and from EI?70 steel with repairs
which are usually permitted for high-alloy tubes, providing
the metal is produced from fresh charges by the improved
(1957) technology. The results of measurements of power
consumption and heating up can be utilised for an approx-
imate evaluation of these parameters during piercing of
other austenitic steels. There are 6 figures, 3 tables
and 6 Soviet references.

ABSTRACT: A considerable increase ii the rate of production of medium-
and large-diameter high-alloy tubes was obtained by
increasing the degree of al.:,ngation to optimum values during
the first and subsequant plerclng operation-s. The new
pz-a!::tlc.e -was based on the '11-alloifixag considerations:
1) Cracks and other defe,-.ts i/Ahich are usually observed
on the internal surf ace of P1er,-t--.,d billets appear not only
as a result of stresses a-,ting on metal in the zone of the
piercing cone, but also duG tG stresses in the cone of
rolling (in the zone of deformation of metal between the
rolls, mandrel and guides). 2) A desrease in the
non-u-nifortwLty of deformation w1h1ch -Js a !~haracterlstlc

TM: The authors report on the resillts of a study of the content and

The concentration of Go and Tl In the mineral' dalts studied 13 not ilidustrially
worthwhile. The Sr content In some waters and salts attains up to O.Ol - D. 1%,
and sometimes up to 1%, however, their processing is for the meanwhile inexpe-
dient, in view of the large stores of Sr in ores. Slimms and dayey materials,
of salt rocks and lake-bottom do osits are always enrichad with Rb and usually
contain it In a ratio of n - 10N. These-products may~be contider4d'aa a -

In magnesium plants are of practical Importanae'as rait Rb sources at the present
time. The electrolyte contains 0.03 - 0.04% Rb. A new method Ur worked out for
extracting Rb from spent-eleotrolytes by the use'of ion-exchange. M is.also
concentrated in slime and clayey materials, but, In contradistinction to'Rb
which then passes Into the solid-phasi, LI together with B remain In eutonic
solutions. Boron-bearing strata of salts and salt bosses contain up zo 0.1%
L120, In the course of processing these products for potash manure ana boron
products, it will probably be possible to extraot M by tne way. Another
possible source of Li extraction ay be the brines of salt lalkes and underground
waters contkining (1 - 2) - 10 % Li, inthe course of their complex processing

and the current I which circulates along the orbit during the capturing

manner in wkick I changes according to time duriag the capturing period.
This is Possible by taking into account that the capturing angle 2
which is contained in the expression far i6ff (effective average zuz~er
of revolution of the electron if there is a space charge in the chuber)
is a function of the, radius of iastantemous radius ri. On the front of
the impulse injection electron energy and r increase. The angle and
consequently also I, increase rapidly on this occasion after which they
decrease slowly. At tko rear front of the impulse injection the current
increases slowly with the decreasing of r but it then decreases rapid-
ly again. The equation Is derived in whiel the capturing processes of
Kerst and Barden are contained as special cases. This equation in Sol-

obtained. This amplitude increases with an increase of the current in

ABSTRACT: Experiments were made here, in order to measure the currents
circulating in the vacuum-chamber of a betatron during the
time of capture and in order to determine the relative
efficiency of the capture in different impulse-injoction-
domains. The experiments were performed in the betatron of
the Leningrad Polytechnic Institute (E V - 15 HeV). The current-
measuring method employed was with some modifications that

showed that the betatron in operating position possesses

injector. A similar relation between the adjustment of the
betatron to a maximum fi and the maximum-r-ray-discharge,
although somewhat less distinct, exists upon modification of

ABSTRACT: Various authors have already suggested niechanionis for the
capture of electrons in a betatron (Refs 1-4)- However, ac-
cording to the opinion of the authors of the present paper,
tva more effects must be considered which may vary the
amplitudes of the radial oscillations of the electrons
considerably by the capture of part of these electrons. The
first effect is shown by a diagram, which represents the
orbit of the electron beam in the chamber during a period
of the radial oscillations. In this case the orbit around
which the radial oscillations happen to develop has the shape
of a periodic curve, and its period is equal to that of the
radial oscillations. The orbit of the electron is distorted

tions of the electron emitted in the direction of the ex-
ternal chamber wall will decrease monotonously. From the
point of view of the effect inventirgated such electrons are
easily captured as were emitted by the injector in the direc-
tion of the external wall of the chamber. 13,~sides the above
investiGated effect there must also be an interaction between
those beams which circulate one behind the other. The beam
probablY retains its band-like shape for several circulations.
T
,!nder these conditions a force will act upon the electron
which will vary in a very complicated manner in the course
of time; it may either increase or reduce the amplitudes of
radial oscillations. The first effact is reduced to a mono-
tonous variation of the electron radial osciliations (which
are injected in the direction of the outer chamber wall) as
a result of interaction occurring on the edges of the beam.
The second effect is reduced to the scattering of electrons
on the inhomogeneities in space charge distribution. There
are 1 figure and 5 references, 3 of which are Soviet.

ABSTRACT: In the chamber -'% the betatron a circulatovy current of electrons
exists durinp~ e time of capture. T'his non-steady-state current,
as it is ca: by the authors, is the subject matter of the study
described in this paper. The study is of a purely experimental
nature. Two methods of operation of the betatron are considered:
a normal operation when the g4mma-,j;~qiation is present, and the
constant field operation. In the hormal operation the intensity of
gamma-radiation was 5 to 7 roentgen, the amplitude of the magnetic
field.was 4,050 oersteds, and the amplitude of the injection im-
pulse was 30 to 50 kv. In the constant field method the amplitudV
of the magnetic field was 0 to 40 oersteds and the amplitude of
the injection impulse did not exceed 10 kv. In the latter

battery, and the time duration of the injectionoiMPU15e Was
purposely increased to between 30 and 50 /t sec. The coil placed
on the vacuum chamber had 500 to 1,000 turns. The signal obtained
in this coil was first preamplified, titen passed through an
iterated circuit of R = 70,000 ohms and C = 7,000 pit f, and
amplified again before being passed through the oscilloscope.
The amplifying circuit was checked, and it was observed that no
distortions were introduced either in the shape or in the amplitude
of the impulse. During the capture time when the beam begins to
circulate within the chamber, not coming in contact with its ex-
ternal walls, the emitted electrons increase the magnitude of the
current, this increase constituting the non-steady-state current.
The time intervals between the injection impulses weve measu-ed
on the oscilloscope. The magnitude of the error in measuring
the non-steady-state cQrrent is determined from the natural noise
of the amplifier and the degvee of homing of the injection circuit;
it did not exceed approximately 5 per cent. The results of the
study show that the magnitude of the average number of revolutions

the radial coordinate rN of the injection filament decreases.
The magnitude of n begins to remain constant at the moment when
almost all the electrons have been emitted within the limits of 'the
capture angle and the orbital current begins to decrease. At that
moment the gamma-radiation reachesits maximum value. It is de-
scribed how this frct can be used for simple adjustment of the
electrons in the betatron; it is stated that the method is used
in factories for unsealed betatron ci.-iiibers of sizes sufficiently
small to be placed on a table. A relationship is given between
the magnitude of the non-steady-state current at the time of
capture and the current caused by the electrons emitted by the
injector. As the emission current increases, the number n of
revolutionB.decreases from 6-8 to about 2-3, or even less. The
greatest value of the non-steady-state current never reached more
than one half of the calculated value, which does not include the
firot-turn electrons. It was observed that the magnitude of n
cannot be clearly defined as a function of the magnetic field,
and that in the constant field method the magnitude of n fell
considerably after several months of betatron operation. As n

current change. Measurements of this current show it to equal
50 to 6o% of the maximum possible value of the orbital current.
In the experiments described, no captured current was observed:
not because it does not exist but because it was too small to be
recorded by the measurement method used. Teumin, M. I., Oks, 1.0.,

the amount of the charge caught by the probe, and this
quantity is proportional to the density of electrons
at the position of the probe. The size of the current
is measured by means of a coil, wound around the
chamber, whose signal after amplification and time
integration is fed to the input of an oscillograph
with slave scanning. The input signal is, at every
moment, proportional to the instantaneous naf.,,nitude
of the nonstationary current in the chamber. The
apparatus registero the curront distribution at the
moment when the radius of the injected electrons I*

to a half-wave of a sinUSoid of approximately 40 ~, sec
duration and of an amplitude It to 8 kv. Prior to
measurements the Injector is always adjusted to yield
a maximum value of the nonstationary current for the
given emission from the injector. Figures 2a and 2b

that the variation in I/Imax with the Injection current

have chosen and not due to processes occurring in the
camera. Figure 2b shows two clear miniminis correspond-

TEXT: The betatron described here consists of two solenoids telescoped
within each other (Fig. 1) which are separated by two glass tubes. Details
of the construction and the elictron injection are discussed. Two quartz
reflectors are utilized for securing the stability of the electron motion.
L. A. Rivlin is mentioned in this connection. The bremastrahlung ras measur-
ed with a scintillation counter, the gamma radiation output was observed
in different phases of the electron injection and at different potentials
on the reflectors. As compared to similar constructions, the betatron
described offers the advantage that its intensity can be considerably
augmented by increasing the length of the system. It is said to be well
suited for certain purposes. The authors thank Professor A. P~ Komar
for his interest and advice. There is 1 figure.

TEXT: An ironless cylindrical betatron model in which the electron motion
was axially stabilized by electrostatic reflectors was reported in a
previous paper (Yu. S. Korobochko and K. S. Shilkov, ZhTF, XXX' tic. 8, 981,
1960). Since the negatively charged electrosta 'tic reflectors had been found
to hinder particle injection, the second model had two additional magnetic
lenses (Fig. 1) to provide with axial focusing.' The equilibrium orbital
radius was 40 Mm, the outer coil haa one turn -per cm, its diameter--wa%157=-
and its len-gth 600 mm. The innei-coil had 5 turns per cm, a diameteT-of
40 mm and a length of 600 mm. Five of the turns of the reflecting--lenses -
were connec-ted in series to an outer-coil and ten turns to an outer-d-c or--
a-c sources The reflectance of the lenses could be varied. A Kerst in-
Jector was fed with voltage pulses of 15 kksec and amplitudes up to 35 ky,

!ABSTRACT: This theoretical paper is concerned with the coherent peaks In the

and by G.Darbellini, G. Bologna, G,Dlambrinir and P.G.Murtas (Phys.Rov.Lett.t 8, 454,
11962). Moderately high energy (tens of MeV) incident electrons are consideredgrather

TEXT; Rigid foams used presently in radio-communication apparatus
have dielectric constant nearly equal to unity and a small loss
angle. This makes it difficult to measure their characteristics
at frequencies as high as 300 megacycles. The,authors 6volved an
improved variant of the resonance method for moasurements at

A h!Sh Crequency signal generator was fed from a stabilized
voltage source and connected to a measuring circuit comprising a
remote controlled capacitor made of circular discs in air with
vernier adjustment, and.a thick silvered tube. The galvanometer
was connected through a high frequency detector to a loop wea'Aly
coupled inductively with the measuring circuit. The measuring

constant, the capacitor was adjusted to achieve resonance without
the sample incircult. The dielectric constant of the material
was determined.from the ratio of thickness of the material to the
distance between the capacitor discs in air at resonance. The
tangent of the loss angle was calculated as a product of frequency,
capacitance of.the sample and-of its equivalent resistance. The
equivalent resistance was determined by measuring current in the
circuit at resonance with and without the sample, and thirdly
with the calibrated non-inductive resistance in the circuit.
Assuming-tliat loss current through the-dielectric is very small
and choosing sudh value of the resistance that the difference
between currents in the circuit, with and without the resistance,
