phic axis, and a suitable trigonometric power series was fitted to the points.Those
curves differ considerably in shape from case to case. Whon the crystal symmetry is
such that tho period of the microhardnasa curve is; 1200, the microlinrdness dopends
not only on the plane to which the scratch is parallel, but also on the direction
in which it is traversed. This difference can amount to 30% In In2Te.3. In some cas-
es the authors plot other crystal properties together with the microhaf~neBs. Parti-
cularly striking is the agreement between therather involved shape of the mic~ohard-
ness curve for the (0001) face of Bi and that of the curve relating direction and
intensity of the Hall field. The addition to Bi of small quantities of Te or Pb,
which oppositely affect the election/hole ratio, distort the microhardness curve
strongly and quite differently. The authors argue that it should be possible to
obtain information concerning,the band structure and the shape of the Fermi surface'
from microhardness anisotropy measurements. The authors characterize their aigu-
ments, as "phenomenological"-and "purely formal". Orig.art.hast 4 formulas, 4 fi7

TRA34SIATION: The scratching method was used to Investigate the anisotropy o:r the
raicrobardness:of Sb,2Se3 crystals on the planes (109), (010), and (001). It Is shown
that the magnitude of the microhardness, and also the external form of the si.,ratches,
depends essentially on the direction of the scratching on the investigated fBLce. On
the (010) plane the maximum of the microbardress is observed in the scratch diree-
tions and (501). An interpretation of -the character of the dependence of the
.(301)
mirrohardna.PS on the d1rection on the (010) face is difficult. Apparently, in Sb2Se3
crystals the slip occurs along the (010) - plane in the ( 100) direction. On the (001)
plane the minimum of hardness is observed close to the (IM) direction., and on the
-(100) plane the greatest hardness is in the (010) direction, i.e., perpendicular to
the emergence of the, cleavage plane on the. (.U)O) face. It is also shown thct in all
'directions the bardnetis in scratching decreases upon illumination, i.e., a photo-
mechanical effect talLes place. V. Osvenskly.

ABSTRACT: The density and coefficient of thermal expansion of alloys in the Se-In
system are measured fi well as the viscosity of the corresponding melts to determine
whether grouping of impurity atoms in selenium actually takes place. It is found that
these characteristics chEmge in a complex manner as the indium concentration in in-
creased. The authozs feel that the resultant data confirm the hypothesis of grouping
of' indium atoms and also indicate that the indium atoms (complexes) are incorporated
in chains made up of selenium atoms rather than being distributed among them. (From

Abstract : The author describes the method of nondestructive testing
based on ultrasonic vibrations of continuously varying
frequency. This method is widely used in industry. Sev-
eral instruments for thickness measurements (up to 20 mm)
or for flaw detection have been Introduced. The author
finds the best conditions of performance of the testing
instruments and introduces a "coefficient of range" as a
ratio of minimum to maximum fundamental longitudinal vi-
brations. The accuracy of measurements is Improved when
this ratio is as low as possible. Five photographs and

ABSTRACT: The principle of the method mentioned in the title is based on
the measurement of the mechanical resistance on a point of the
surface under investigation by means of the reaction on the

for the detection of gluing or soldering defects. Figure 1
shows the scheme of the testing instrument which consista of
two piezoelements and one feeler. The vibration range of the
instrument is between 2 and 7 kilocycles. The first piezaele-
ment serves as sound emitter, the second is connected to an
amplifier and reacts on the mechanical impedance of the object

ABSTRACT: -A considerable drawback of the detection of defects in material
according to the ultrasonic echo method is the so-called "dead
zone" in which no defect can be observed. A reduction of this
zone can be achieved in such a way as to conduct ultrasonic
waves from two opposite sides into the test object. For this
purpose a crack detector is used for which a movable time mark
is used in the depth indicator and the distance from the re-
flecting surface thus can be measured. An appliance of this
kind is the crack detector V4-7I (Ref) in which a point impulse
is used as a time mark. Its polarity is opposite with regard to
the echo signal. The described reduction of the dead zone cannot
be carried out by means of appliances of a depth measuring system
(as for example UZD-7N or foreign appliances) other than that of

ABSTRACT: The mechanic resistance of the test object observed during the
application of the ultrasonic resonance method, can ba used for
the detection of defects in material, since the sender (S) Of
the resonanc~e appliance reacts to a change of the msohankc re--
sistance, This, however, only holds good in a few special :~asas.
The new aooustio testing method for adhesive and soldering con.,
nections, offering wider possibilities of application, uses
lower sound frequencies, opposite to the resonance method.. A
rod is used as (S) which causes elastic oscillatione in the
test object. At the same time the mechanic resistant-.F.6 is mea.-
sured from the reaction power of the object to (S), and the
method is therefore called "reaction method". Professor A. V.

the first time used this measuring principle for vibration
investigations. The measuring method in principle consists
of the fact that the (S), contacting the intermediate layer
over a faulty point (Fig 1), receives a smaller "reaction
power" than that over a faulty point (the greater this dif-
ference, the more reliable the determination). The graph of
the applied (S) (Fig 2) shows that it contained a piezoele-
ment of barium titanate. The (S) can work within the scope
of frequencies of 2000 -- 7000 cycles. After an explanation
of the measuring method it, is found that the glui.ag of ma-
terials with a lower modulus of elasticity cannot be tested
according to the described method. The present tet3ts were
carried out with standard appliances, a sound generator
7G--10 and amplifyer 28--IM; different kinds of gluings were
e-amined. The method can also be used for testing adhesive
layers of bimetallic connections. There are 2 figures and

TITLE. Acoustic impedance 11AA-1 (IAD-1) flaw detector
PERIODICAL: Byulleten' tekhniko-ekonomicheskoy informatsii, no..5, ic,161, 47-48
TEXT: The IAD-1 flaw detector, designed by some (not named) Scientific
Research Institutes and fabricated by the Kishinev "Elektrotochpribor" Plant is
intended for the detection of defects in multi-layer glued and soldered struc-
tures. The device is based on the acoustic impedance control method (which up
to 1960 was called 1'reactiQn method") utilizing the dependence of the full
mechanical resistance measured from the part surface (mechanical impedance) on
the presence of adhesion between the elements of the structure being checked.
The mechanical impedance is determined by the amplitude of the part reactive
power on the oscillating pickup being in contact with it. The illustration
shows the block diagram of the flaw detector. Piezoelement 1 excited by the
voltage of sound generator 2 emits elastic oscillations to rod 3 made of organic
glass ( orgsteklo"). Steel cylinder 4 inbreases the effectiveness of emission.
On the opposite end of rod 3 force-measuring piezoelement 5 is mounted. The

voltage on piezoelement 5 is proportional to its deformation and, consequently,
to the reactive power causing this deformation. Piezoelement 5 is connected to
amplifier 6 charged on dial indicator 7 and relay unit 8. The pickup is in
contact with the part via contact-finger 9. The absence of adhesion between the
sheathing and the remaining elements of the structure being checked causes a
decrease ii, the mechanical impedance which is determined by the reduction of the
signal level at the amplifier output. In this way the flaw is detected by a
decrease in pointer deviation of output indicator 7.
Simultaneously relay unit 8 starts operating switching on
indicating lamp 10 located in the pickup. The operating,
frequency of the IAD-l flaw detector covers a range of 2
1-8 kc. The device weighs about 8 kg, and is supplied
from the 220 v a-c mains. The required poVer is 110 v-
amp. The thickness limit of the sheathing which still
yields good results is 1.5 mm for duralumin and.2-2.5 mm
for glass-textolite.' There is I figure.

ABSTRACT: one of the most univerriall and effective methods for Inspection of glued,
soldered, and thermo-diffusion joints in multilayer structures is the acoustic impedance
method. This method is based on evaluation of.the mechanical Impedance of an article on
excitation of flexural vibrations In It, and to successfully and widely used in industry for
detection of defective joints between the skin and and rigid elements (spar, rib, etc.) or
fillers (foam layer, honeyc)mb). Inspection Is by the 1AD-1 defectoscopes, an exporimenLrd

series of which was produced by the "Elektrotochpribor" plant in 1960. The authors have
now developed the JAD-2 acoustic Impedance defectoscope, an improved version of 1AD-1.
Ilie block diagram of the IAD-2 Is shown in Fig. 1 of the Enclosure. The sound generator
1 feeds the piezoelectric element 2 which excites elastic vibrations in the bar 3 of the
pick-up. At the lower end of the bar, the force-measuring piezoelectric element 4 Is
located and connected to the Input of amplifier 5. The pick-up touches the article to be
inspected through contact tip 6. When the pick;--up Is not pressed against the article, the
force acting on the piezoelectric element 4 is determined only by the Inertia resistance
of the contact tip, which IS Small due to the small mass of the tip and the relatively low
frequency used. Therefore, in that condition, the electric potential of the element is close
to zero. This potential increases substantially when the pick-up exerts pressure on the
article. At the same exerted pressure, the potential increase Is greater at higher values
of mechanical impedance of the article at the contact point with the pick-up. A defect of a
connection inside the article causes a sharp decrease of mechanical impedance, and
therefore of the potential of the force-measuring piezoelectric element. Potential varla-
tione of the hensor are indicated by an electric dial gage 7 at the output of an amplifier 5.
Card 2/6
ACCESSION NR: AT4013979
At a cert:-Lin v;duo of the dial indicati-n, relay 8 switches on the signal lamp 9. The
defectoscolic IAD-2 works with a pick-up of the type DI-1 (Fig. 2 of the Enclosure). The
emitting 1 and foree-measuring 2 piezoelectric elements are of barium Utanate. The
sound-conducting bar 3 is of organic glass and has the form of a truncated cone. A steel
cylinder 4 serves as a relecting mass and Increases the effectiveness of the emitting
piezoelectric element 1. The contact tip 5 Is of wear-resistant hardened steel ShMil.5
with -a radius of curvature of 20 mm. In bar 3, near the emitter, a shield 6 cuts the
capacitative coupling between elements 1 and 2. Shielded leads 7 connect the pick-up to
the defectoscope, and are protected and supported by a steel coil spring 8. A brass ring
9 protects the element 2 from mechanical damage and shields It from electrical distur-
bances. A signal lamp 10 is housed in the body 11 of the pick-up. The fundamental
electrical scheme has been described by the authors In detail. The range of frequencies of
the sound generator in the defectoscope Is 1 to 8 kilocycles/sec. The 1AD-2 defectoscope
can be used as part of a semi-automatic Installation for mechanized inspection, with recording
of the results on thermoelectric paper. The defectoscope Is fed from a 220-volt supply
circuit, and the power requirement does not exceed 100 W. The weight is 1.1 kg. During

ACCESSION NR- AT4013979
inspection of joints, the operator moves the pick-up smoothly, pressing Its tip lightly
against the surface of We inspected article. The presence of a defect is reported by a
signal light installed in the pick-up. The possibilities of the acoustic Impedance method
of inspection, and the ftming procedures for instruments, have already been discussed In
the literature by Yu. V. Lange (Zavodskaya Laboratorlya, XXVI, 7 842(1960)). Laboratory
and productiori tests carried out with the IAD-2 defectoscope have shown its considerable
advantages over the LAD-1. For example, inspection of honeycomb sandwich panels
having a thin (0. 25 mm) duraluminum skin and large honeycomb (side=Omm) cells, when
performed with the IAD-1, deff!ctoseope,is possible only when a special and inconvenient
pick-up Is applied. With the IAD-2j the same task can be performed with a standard
pick-up. OrIg. art. has: 4 figures.

ABSTRACT: This Author Certificate presents a flaw detector for inspecting nonmetallic
films, multilayer constructions, and other parts, e.g.., glass plastics, by the method
of free vibrations. The flaw detector contains an electromechanical vibrator, an
elastic vibration receiver, electric band-pass filtersq~ amplifiersj and detectors*
'To*increase the inspecticn reliability, a two-channel circuit is connected in the
receiver circuit. A filter with a pass band, corresponding to the frequencies of the
vibration maximum of the. part in the region of the flaw, is placed in one channel.
To measure the ratio of tile signal amplitudes, a ratiometer operating from the
detectors connected at tile outputs of each channel in used.''

ABSTRACT: The results of experimental studies of the performance of the UVFD-1
velocimetric flaw detector are Given. The probe head, which contains transmitting and
receiving vibrators with a fixed distance X between them, is placed on the surface of
the article (Bee Fig. 1). The elastic flexural wave from the transmitting vibrator is
propagated with velocity vg which is a function of the layer thielmess. The propaga..
tion velocity in a flaw is lower than in a segment without a flaw. This changes the
phase of tho wave. Laboroory teats were made with an MOOl galvanometer and an N-700
loop oscillograph. Testahore made with PT sheet textolite of 1360 x 740 x 10 mm,
The velocimetric method can be used to detect laminations and fracture zones at a
depth of up to 26 mm in laminated plastics and in structure- containing nonmetallic
layers.
