I ACUSSION NR: AP4041382 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".

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.

This principle was applied for the first time by Professc,r A. V. Rimakiy-Korsakov (Acoustics Institute of the AS USSR) for the measurement of mechanical resistancesin his investigation. of vibration. The method suggeszed by the author mainly aerves 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 Card 1/2 under investigation. This impedance is relevant if there is a A New Acoustic Method of Detecting Defects and Some Results of Its Application good bond of the soldering or gluing material with the base material; it decreases, however, on those spots where thereis a gluing or soldering defect, where the 1,pper layer rests on loosely, and vibrates on its own.

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 Card 1/1 V4-7I.

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. Rimskiy.-Korsakov (Akusticheaki-Y in8titut Akademii. nauk SSSR) Card 1/2 (Institute for Acoustics of the Academir of Sciences~, USSR) f01, New Methods for Applying Elastic Oscillations for the SOV/32-25-7-22/5C Detection of Defects in Material 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 I Soviet reference. Card 2/2 28 (5) AUTHORS: Shrayber, D. S., Lange: Yu. V.

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 Card 1/2 21896 S11931611000100510061006 Acoustic impedance 11-AA-1 (IAD-1) ... A004/A104 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.

Moscow, Me,,tallurgizdat, 1963, 94-97 TOPIC TAGS: acoustic impedance -defectOBcope, defectoscope, mechanical impedance, joint inspection, metal joint 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 Carcl 1/6 ACCESSION NR: AT4013979 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 t:ard 3/6 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.

ORG: none TITLE; A study of the performance characteri8ties of the ultrasonio'velocimetric method of flaw detection k~ SOURCE: Zavodskaya laboratoriya, v. 32, no. 1p 1966, 34-38 TOPIC TAGS: ultrasonic flaw detector, laminated plastic, elastic wave, lamination, phase meter, performance test/ UVFD-1 ultrasonic flaw detector ~A \0 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.
