ABSTRACM.. The mechanism of phase hardening (diXjq_and reverse martensitic trans-
formation) was studied in very low carbon Fe-Ni-Ti Valloys. The established me-
chanism, involving the formation of fine subi-truFfudre in the phase hardened auste-,
nite, proved inadequate.in explaining the large increases in strength which were-
commonly observed. The compositions and temperatures of the alloys us~a are
shown in Table 1.

The ingots were homogenized at 11500C for~18 hrs, drawn into rounds, sectioned in-
to samples and annealed at 11000C for 2 hrs,(vacuum). The austenitic samples were
subsequently cooled,from room temperature to -1960C to induce the y-a transforma-
tion. The resulting substructure was analyzed by x-ray methods: harmonic analy-
as used to measure the block size and the microdistortion and the data were re-'
corded in terms of specific dilatation, AO/tanO. For each of the alloys the me-
,chanical properties are given in relation to ihe block size. The characteristic

block dimensions-'and the specific dilatation for the direct martensitic transforma-
tion did not change with increase in Ti content. The reverse transformation--back
to austenite--was done by immersing the specimens in hot oil baths and heating at
rates of 80-100 deg/sec. In this case, the block dimensions (substructure) of the
austenite was again similar for alloys with or without Ti. However, significant
differences in the yield strength of the austenite, formed by reverse transforma-
tion of martensite, were induced by changes in the rate of heating or the tempera-
ture of beating. It was demonstratej, that the large rise in strengthening in alloys~
with Ti could be attributed to agingi%ffects. It was postulated 'that the higher
strength of H27Ti (resulting fi;6~pfi_ase hardening by slow heating) was due to ccm-
bined aging and phase hardening. Wedge.shaped specimens were heated electrically
after being quenched into liquid nitrogen in order to produce temperature gra
Aients
across the specimens. The change in hardness was given as a function of dis nce
along th .a specimens or equivalently for changing aging conditions. Hardne kin-
creased with aging, indicating the presence of some form of disperst precipitate
resulting from the Ti addition. Thus maximum hardening could be achieved in Fe-Ni-
.-Ti alloys as a result of combined aging and phase hardening if the heating rate is
slow or if the heating temperature is high enough. Orig. art. has: 6 figures, 5

ABSTRACT: The authors consider, onthe geometrical optics
approximation (Ref 8), amplitude and phase fluctuations
of radio waves propagated in a turbulent medium in the
presence of a plane separation boundary. In.this case,
the resultant~field at the detector e is given by the
sum. of the direct wave and the wave reflected from the
separation boundary (Figure 1). The two fields are given
by Eq (1) in which R and 9 are the modulus and the
phase of the Fresnel refleqtion coefficient, respectively.
The amplitudes and phases of the signal's can be written
in the form given by Eq (2), where the quantities with
subscript .11011 are mean values and AE. and are
the fluctuation comDonents of the corresponding quantiti
les.

fluctuations, one has the approximate relations given
by Eqs (6) and (7) and the phase of the resultant signal
is given by Eqs (8) and (9). Assuming that the medium

The Effect of the Separation Boundary on the Fluctuations of Radio
Waves Propagated in a Non-homogene-Ous MediUM
It is clear from Eq (16) that, under the above assiLmptions,
the amplitude and phase fluctuations in the resultant
signal are equal in the distant zone. However, the
dependence of the intensity of fluctuations on the wave-
length, the parameter Ll and the distance r (Figure 1)
1
may be quite different from that in an infinitelmedium.
A comparison of this theory with experiment shows good
agreement and hence it is clear that in practice it is
necessary to take Into account the effect of the bound"y
on the fluctuations. The above solution was obtained for
the plane problem. It would bo desirable to obtain a
solution for a spherical Earth, particularly in the regions
where geometrical optics approximation does not hold.

ABSTRACT: The results ofan experimental measurement of the
fluctuation of the phase front-r'during the propagation.of
vertically polarized radio .w�,V_6_S1Bover'the sea surface are
.roported. The frequency employed was 3 000-Mels and the
experiments were carried out under various meteorological
conditions during July;:;Sept-emb,er and October-pacember
over a sea route having a length- of 33 km. The differential
method of measurement was.,empX-oyed, in which the fluctua-
t-ivns of the phase differences of the signals received by.
d1vers�ty antennae were-employed to determine the intensity
and the decorrelatlon of the phase fluctuations at various
points of the vrave front. In order to reduce the effect
of the boundary refraction, the receiving systern were
situated at distances of 2, 5, 10, 30 and 100 m from the

were employed. The antennae were situated about 4 gi-above
the sea surface. The error in the measurement 8f the

If the amplitude of the received signals varled as much
as 60 db. The measurement showed that as a rule the

ABSTRACT: Earlier papers dealing with this subject mainly take the
amplitude fluctuations of radio signals into account. The
phase fluctuations were investigated only in the zone of
direct visibility (mainly over the mainland). The present
paper deals with the least investigated problem, namely the
experimental inyestigation of phase-front fluctuations over
the sea. Measurements were carried out on the wave X - 10 em
in the case of vertical polarization during the period of from
July to September and October to December along a line of
33 km longth'leading exclusively over the sea within the
boundaries of the "illuminated zone". the "half-shade" and
Card 1/4 "shade". In these investigations the differential method was
The Fluctuatione.of the Phase Fronts in the SOV/20-125-5-~18/61

usedp which (by measurement of the pulsation of the phase
difference of the electromotive force in some reception
antennas) make determination of the amount and the degree of
deoorrelation of wave front fluctuations in distributedly
arranged measuring points. The arrangement of 6 measuring
-antennas along a straight line for this purpose is described.
In this way it was possible to measure phase fluctuations
within the frequency range of from 0.01 to 100 cycles. Besides,
provision was-made for the possibility of filtering and sepamte
indication of low-frequency 0,~ 0-3 cycles) and high-
frequency ( > 0-3 cycles) (i.e. of the so-called "slow" and
"fast") fluctuations. According to the results obtained by
these measurements the fluctuations of phase differences were,
with r,are exceptions, distributed in accordance w:Lth the
normal law. Howeyer*t the fluctuations observed can be
ooordinated.to the steady random processes only with certain
,reservations, for various cases of phase difference
fluctuations of signals were detected. The dependence of
fluctuation intensity on the intervals between the measuring
Card 2/4 points remained qualitatively equal in the case of all

experiments.-The character of the height-dependence of
intensity was considerably more manifold, and therefore it
also served as a basis for the classification of experiments.
All measurements may be subdivided into 4 main groups:
1) Quasisteady standard type of phase-fluctuationa. Most
experiments belong to this group which is characterized by
a monotonous reduction of fluctuation intensity with an
increasing height of the transmitter. Such a dependence is
found with propagation within a local isotropic troposphere
over a plane separating surface. These measurements have a
high degree of-steadiness and good reproducibility of the
intensity and spectral composition of fluctuations. 2) The
nonsteady standard type of fluctuations is characterized by
a considerable non-steadiness of the fluctuations. 3) The
anomalous type of phase-fluctuations: in measurements of this
group the height-dependence differs considerably from that
of the standaia type. 4) The "flaring up" of fluctuations.
This state usually did not last longer than a few dozen
minutes, after which the usual state of the fluctuations was

In April 1954, Prof. D. V. Ageyev suggested to the author
the Investigation of the compensation method of reducing
nonlinear distortions. The negative feedback which is
widely applied to reduce nonlinearities in large 1.f
amplifiers has some essential deficiencies. The author
investigates the basic theoretical aspects of the compen-
sating method which consists in compensating by shifting
the distorted voltages (or currents) by 180u. He-
presents.connection diagrams, finds the stability of the
method, the characteristics of the compensating cir-
cuit, and finally checks the method experimentally. He
finds that an 8 to 10 fold reduction of nonlinear

effective than that of the usual limitation. The further
investigations in this direction showed principially new

similar systems. In this method the separation of signal
and interference by using two differences between the pulse
interference and the sienal - the difference with respect to
the amplitude and to the spectrum - is realized. Various

together with a limiter an essentially greater effectiveness
in the suppression of pulse interference is obtained then is
the case with using a simple limiter. The characteristics of
the first transformer must be of such a kind that 1.-
the greatest ratio between the interference level and the
level of the eff~~ctive signal at the input of the limiter is
securedv and 2*- the limitation leads to such a transformation
of the form of the interference-spectrum that in it the second
transformer can effect the selection of the signal with the
greatest efficiency. In the reception of radio programs these
demands were met to a greatest extent by an input transformer
with a resonance form of the frequency characteristic. In this
the resonance frequency must be sufficiently high as it must be
outside of the limits of the basic band in the spectrum of
the (inte 1 igence) ef f ec tivd sicnal. There are 8 f1gures and 4 ref-

PERIODICAL! Vostnik Moskovskogo universiteta. Seriya 3, fizika,
antronomiya/5no. 6, 1960, 8-9
TEXT: Whereas interaction between light and metal has been made the
object of accurate research for oases in which the term 49J/c of the
Maxwell equations may be neglected, the present paper deals with the more
complicated problem of the case j ~ 0. The conduct of current through
metal.must produce an effect upon its properties and thus also upon the
properties of the light reflected by it. It was found that the reflective
power of the metalis changed during the passage of current. According
to the nature of the metal,, a relative change in the reflection coefficient
occurs by. tenth parts of percents at current densities of I - 3 a/MM2 or
7 - 10 a/mm2. Measurement of. 6 - (I - loylo was carried out by means of
an apparatus similar to thut developed by 0. S. Krinchik (1959). The

lamellas having a crose.section of 0.'5 s 6 =2. Measurements were
carried out for white light. Stabilization of the current of the light
source permitted measurementsp whose errors did not exceed 0.01%. The
effect was measured, which in analogy to magnetic optics may be described
as meridional effect. Thevector I of current density lies in the plane
of incidence of light. The experimental datafor the p-wave are given in
the table
(In the case.of the s-wave this effect lacked nearly
entirely The angle of incidence of light was 4'50. By p-wave the light
beam is understood, which is polarized in such a manner that the electric
vector lies in the plane of incidence of light. Measurements for Ni and
W were carried out at 3 and 5 a/mM2 more accurately. In the case of other
metals, only--'qualitative measurements were carried out for the purpose
of determining anourat and sign of 6. That an oxide film produced no
effect upon 6 could be seen from the fact that measurements carried out
2 minutes and 24 hours-after polishing agreed within the limits of measur-
ing errors. The change in theintensity of 6 has different signs in dif-
fer4ht metals. In the case of some metals the reflection coefficient

TITLE: Method of increasing-the interference immunity of multi-
channel systems used for high-frequency telephony
PERIODICAL. Vestnik svyazi, no. 1, 1961, 13-14
TEXT: A unit that is able to suppress periodic pulse interferences in
multi-channel systems of high-frequency telephony is briefly described.
The unit has been developed by the Gor'kiy Scientific Research Institute.
It works on the principle of eliminating the signal and also the
interfering pulse. if the.duration of the short interruptions does not
amount to more than 350, then the conversation is still well intelligible,
even under adverse conditions, i.e., if the interruptions have a
frequency of 300-888 cps. The unitloonsists mainly of three subsequent
stages. 1) The first stage separates the interfering pulse from the
mixture of signal and interference, and is used to control all other

stages. This stage consists of a tuned amplifier which is tuned to the
carrier frequency of the inierferen .oes, and its resulting band width is
such that the interference amplitude is amplified maximally compared to
the signal.. 2) The second stage delays the interfering pulse by an
interval which roughly corresponds to its period, and a control pulse is
generated, which corresponds to the duration of the interferencepulaeo
The stage co~aiata of a number of multi-vibrators which are cleared by
pulses of stage 1. 3) The third stage is blocked for the duration of the
control pulse. Every pulse is used to eliminate the following pulse.
Fig. 2 shows a simplified circuit diagram, and the mode of operation is
explained in its legend. The unit has been tested with communication
systems ofthe type B-12 (V-12) at three amplifier stations. The input
has been applied to the socket of the filter K-33 (K-33), and the output
to the control grid of the second amplifier tube of the element BY(VU)
belonging to the system V-12. It has been found that the psophoinetric
interference voltage will drop by a factor of 3 - 25. Transient
interferences and non-linear distortions of the voice signal are much
higher due to the method applied, but intelligibility is maintained even

TEXTs In a previous paper the present author and
R. D. Nuraliyeva (ZhETF, 1959, 36, 1022) pointed out that.the
magnetooptic resonance due to,electronic s-d transitions is t o be
expected-in the ultraviolet region of the spectrum. In the present
.paper an experimental study of this effect is reported. The
apparatus used to.measure the magnetooptic characteristics of
nickel and iron below 2480 A was similar to that described by the
first of the present,-authors in Ref.4. The detecting element was
a ~D3Y-19 (FEU.,18) photomultiplier, while the compensating element
was the vacuum photocell (STsV-4). The spectrograph

field. since it was necessary to measure very small changes in the
intensity-of the reflected light during the magnetization reversal
in ferromagnetic specimens. In order to reduce tbe magnetic flux
leakage, the specimens were in the form of toroids (internal-
diameter 20 mm, external.diameter 30 mm). A pqrt of the surface
of these toroids, having an area of about I cm ,, was kept free of
the magnetizing coil and the light was refle--ced from it. The
specimenswere polished and annealed in vacuum prior to insertion
of the magnetizing coils. Magnetic saturation could be obtained
using 1000 turns and a current of 0.5 A. Fig.2 gives the real and
imaginary parts of tho magnetooptic parameter calculated by
Nuraliyeva, using the optical constants for nickel as given by
R. S. Minor and W. Meyer in Ref.5. FiS.3 gives the relative
change in the real and imaginary parts of the non-diagonal term
of the dielectric constant tensor, i.e. m i = Re(cm)/c1 and,
6 ig is the diagonal term and
