TITLE; Effect of Ultraviolet and X-Rays Upon the Internal Friction of Siiver Chloride PEIRIODICALt Fizika tverdogo tela, 1960, Vol. 2, No. 6, pp. 1107 - 1110 TEXT: The article under review describes the effect of ultraviolet and X-rays upon amplitude-independent internal friction at low frequencies (1, cpg). The internal friction was determined by measuring the logarithmio decrement of damping of the torsional vibrations of AgC1 filaments by means of a relaxator. The behavior of the shear modulus was determined from the square of the vibration frequencJes (f2) . The AgC1 samples were first de- formed (compressed) and ancther part cf the samples was annealed. No satis- factory results., however, could be obtained with the latter (Table). The internal friction was reduced by irradiation, with ultraviolet and X-rays yielding the same action. The following dependence of the intensification Card 112 8IL623 Effect of Ultraviolet and X-Rays Upon the S11 81/160/002/06/11/050 .1-riternal Friction of Silver Chloride B122/BO63 I (or redu,--tion of friction) on the exposure time could be Samples that had beer compressed already es ab' i s hed!: AQ = ~,efore -, were strengthened on irradiation according to the same law.

TITLE: The "Decorating" of Defects in Silver Chloride Crystals A PERIODICAL: Fizika tverdogo tela, 1960, Vol. 2, No. 9, pp. 2270-2275 TEXT: The authors describe a method of "decorating" defects in AgC1 crystals by bringing them into contact with zinc. Two kinds of samples were investigated: a) lamellas rolled down from single crystal to a thickness of Ov4 - 0.5 mm, and then freed of stress by heat treatment. b) Single-crystal lamellas 1.0 - 1.2 mm thick. A polished zinc lamella was pressed onto the samples at room temperature, taken off again after 30 - 45 min, after which the AgCl Was examined under the microscope. At places where Zn had been in contact with AgCl, white spots were observed, which had formed in consequence of the reaction 2AgCl + Zn42A9 + ZnCl 2' After two days, rainbow-colored, ordered rows of spots (Fig. 1) appeared around the contact surface, which were concentrated especially at the grain boundaries (Fig. 2). After having been treated with a photographic Card 1/2 The "Decoratinc-11 of Defects in Silver S/181/60/002/009/031/036 Chloride Crystals B004/BO56 developer, the spots becau!3 black, and were found to be reduced silver which had formed also within the crystals (Fig. 3) at the dislocations. Experiments made at 2000 and 2800C, after the AgC1 samples had previously been deformed in order to produce slide lines, led to the same result. An especially high Ag concentration was found on the slide lines (Fig. 4),L/ vil-,zreas no silver had been separated on the neighboring stress-free places, which apparently contained no defects. The concentration of the Ag spots corresponded to the concentration of the defects. After attaining a maxinum, the concentration of the spots no longer increased, but the silver crystals started growing. Similar but less distinct effects were also cbserved when AgCl was treated with copper. The authors thank Professur A. A. Zhukhovitski for his advice.

Harbin Polytechn. Inst., 1959, Ne. 4, PP. 31 - 42 (Chinese, Russian summary) TEXT: The authors studied the dislocatJ-,n mechanism of slip in crystals of the rock salt type. Bi-refringence bands, s'jserved in polarized light, were compared with results of investigations into the surface relief of lateral crystal faces, obtained by the microinterometrical method. It was established that during the process of slipping the magnitudes of shift at both ends of the slip plane were always equal. The method of etch-pits was used to investigate the distribution of dislocations in crystals during plastic deformation. By comparing the magnitudes of shift in a plastic deformed rock-salt crystal with Card 112 S/137/60/000/010/028/04o A006/A,DO1 Investigation of the Dislocation Mechanism of Slip in Ci-jstals the surface relief of lateral faces, a single-valued correlation of the etch-pit and dislocation was established. It is shown that dislocations of opposite signs are impeded in the slip band; at elevated temperature they are able to move to- ward each other and to be annihilated. There are 19 references. Z.F.

A quartz resonator was employed in the measUrements. -All the metals showed a maxhnwn In this dependence at 40 - 240 Cps. An evaluation of the experimental data for metals, made. from the two standpoints Card 1/2 L 43577-65 ACCESSION NR: AT5009587 of dislocation relaxation and temperature relaxation,- shows that both of these concepts.. do not contradict the experiment. Uthium fluoride crystals were then studied in order to gain further insight into the relative roles of these two mechanisms olf relaxation. -In this case, the study of internal friction in relation to preliminary deformation showed that in lithium fluoride crystals the internal friction and dislocation density remain constant in the region of elastic deformation. As In metals, the rise in Internal friction begins simultaneously with the start of bulk volume plastic deformatiag'. As,the preliminary deformation is increased further, the rise In Internal frictionAffid dislocation density becomes parallel. Lithium fluoride samples sOjected to x-ray bombardment before and after deformation were also studied, and the results are interpreted In terms of point de- fects.

The diagonal rays corresponding to the emergence of edge dislocations are always longer than the other rays corresponding to screw dislocations, A series of photographs are shown of LiF crystals after indentation with the same load and after etching in similar conditions: the crystals contain different additionsi the length of the rays of the stars changes with different degrees of alloying. The lengths of the rays, the yield point and microhardness of the crystals were determined. Card 1/3 5/070/62/007/001/0,-0/022 On tfie relati.ori between E021/E435 The data show that the greater the increase in the yield Duint as -a result of allaying the more pronounced is the shortening of the d-iagonal rays of the stars, Thus. the change in length of diagonal is not a function of the surface changes but of the volume 'hanges in the crystal, Fig.3 shows the relation between the relative change in yield point (x-axis) and the relative change in length of the diagonal- Curve 1 is for a load of 20 g and 2 for 50 g, The beginning of the appearance of elasti-_- or plastic deformation was followed by a photo-elastic method.

TITLE: Investigation of the recovery of internal friction in crys- talline silver chloride SOURCE: Fizika tverdogo tela, v. 6, no. 8, 1964, 2441-2444 TOPIC TAGS: internal friction, recovery dynamics, silver chloride, single crys-tal, activation energy, diffusion mobility, crystal qlattice defect, dislocation immobilization ABSTRACT: The recovery of low-frequency internal friction following. plastic deformation in wire samples of AgCl, either pure or alloyed with 0.012 at.% NaCl, was investigated at 0, 25, and 500C. The frequencies used were 1.5--2.5 cps. The wire samples were obtained from single crystals by pressing and rolling, followed by annealing for 10 hours. A second annealing was used (130C, 1 hour) after the Card 1/3 ACCESSION NR: AP4043367 sample was clamped in the relaxator. The activation energies of the recovery process as a whole were found to be approximately the same for both pure and alloyed samples (0.23 + 0.02 eV) (0-1 + 0.02 and 0.08 + 0.02 eV, respectively). The average value of the activa- tion energy of the diffusion of point defects was found to be 0.23 + 0.02 eV for both pure and alloyed sAmples of AgCl. This indicates: that the recovery process proceeds in the same manner in both pure and alloyed silver chloride. The fact that the recovery activation energy is on the whole lower than the activation energy for the dif-, fusion of point defects indicates that, although the observed de- crease in internal friction following plastic deformation agrees with the theory of Granata, Hikato, and Lucke (Acta Met. v. 7, 470, 1958) the diffusion mechanism is not the only recovery mechanism, and others, with lower activation energy are possible. It is also shown that the dislocation.immobilization is due to diffusion of the intruded Ag+ ions to the dislocations and of the vacancies of these ions to the-dislocations. This is corroborated by the fact that the Card 2/3 ACCESSION NR: AP4043367 value obtained for the activation energy of the diffusion of the point defects which immobilizes the dislocations during the recovery processes (0.23) is intermediate between the activation energies for Ag+ ions (0.15) and vacancies (0.33 eV) in silver chloride, as published in the literature.

The essential feature of the technique consists in observing the stresses in a polycrystalline material (AgC1) and at the same time studying the strains by the method of photoelastic coatings. In the latter method,- a reflecting layer of metallie silver Is deposited on the polycrystal- line AgCI, and an optically sensitive coating is placed on top of that layer. Two patterns of isochromes (one In AgC1 and one in the coating) are then observed on two separate sdreens, the specimens being subjected to loads. - The apparatus and method of operation are described in detail.

Rost kristallov, v. 6, 1965, 129-132 TOPIC TAGS: single crystal growing, -lithium fluoride, uranyl nitrate, crystal dislocation, triboluminescence, hardness, ABSTRACT : LIF single crystals activated with U02(NO3)2 were grown from the melt by the Kyropoulos method. The Infrared absorption spectra of L. IF + U crystals obtained were almost Identical to those of pure LIF. Three methods were used to study the mechanical properties of the crystals: (1) measurement of micrehardness.with a PBff -3 Instrument; (2) compression tests with an Instrument for micromechanical testing of materials; (3) study of the "star" of dislocations formed around the mark of the diamond Indenter. It was found that the Introduction of uranium increases the strength of LiF crystals by one order of magnitude and the microhardness by 20% without changing their transparency in the Infrared. A shortening of the prongs of the "star" showed a decrease In the mobility of dislocations arising during plastic deformation. This decrease is thought to be caused chiefly by the 1/2 ACC Nits AT6002244 formation of a charge on the dislocations by the uranium Ions. An analogy was observed betv;een the mechanical and tribolumineseent properties of LIF + U crystals. It is concluded that the principal part In the phenomenon of triboluminescence In not played by the cloud of excess chaftes, but by the mobility of dislocations.

PP. 139-149 TEXT: Vibratory polishing is an advanced method of surface finishing gas turbine blades. The principle of the process will be seen from Fig.l. The blade 1 is held between two rubber pads 2 and 3 which are fastened in metal holders 4 and 5. The blade is made to vibrate at a rate of 900 - 1500 strokes/min with a straight line translatory motion in the two directions shown by the arrows A and B. The blade is then polished by two abrasive belts 6 and 7 which adhere to the rubber pads and slide over the blades. To ensure good contact between blade and pads the blade must be able to position itself transversely (arrow K) and about the vertical and horizontal axes (arrows D and M). The suspension originally used to achieve this motion is described and was Card 1/6 25616 Problems of the kinematics of vibro-... S/536/60/000/045/005/oo6 E194/Ei84 successful in treating many types of blade. However, in trying to polish turbine blades with small radii of curvature combined with large angles of twist and great depth of profile it was found that a considerable part of the profile remained unpolished. It was found that this occurred because when the angle of pressure between the direction of motion of the blade and the direction of the tangent to the profile is very high the frictional forces increase and the rubber pads are deformed. To reduce the angles of pressure it is necessary to alter the straight line motion in the direction of the arrows B in Fig.1 by oscillatory motion around a certain axis so selected that the pressure angle is not too great at any section of the blade. The method offinding the optimum position of the axis of rotation is then discussed first for simple cases and later for a blade with profile of variable curvature, Geometrical constructions for determining the best axis of rotation are given. With the new type of motion of the blade during polishing the facilities previously provided for the blade to position itself are not only unnecessary but positively harmful. Accordingly a new design of the suspension was prepared, which is illustrated in Fig-,9 in which vertical motion of the blade is Card 2/6 25416 S/536/6c/ooo/o45/005/oo6 Problems of the kinematics of vibro-- Ei:94/El84 achieved not by a shaft sliding through bea-rings but by bending of steel tapes forming an elastic parallelogram. In designing the suspension free ve-rtical motion must be combin'ed with sufficient torsional rigidity. As it was difficult to design the spring paralielo.-ram theoretically, tests were made oFn special models. In th-A final suspension the vertical displacement is provided by a crank mechanism 2 which drives a frame 5 suspended on two flat spring I. Horizontal-positioning of the b.1ades is permitted by two springs L. A further crank 6 provides the rotatory motion. The springs I are made of steel 160 MM Wide, or two strips 80 mm wide, 100 mm-long and 1 mm. thick. The springs L are 100 mm wide, 28 mm long and o.6 mm thick. With this suspension the blade surfaces are satisfactorily polished. There are 9 figures. Card 3/6 SHASKOLISKIY, B.V., kand.tekhn.nauk-; YEVG-AIIEV, G.B., inzh.; IAPSHIN, N.P., in Z- 1 -1.

The operation of this machine is as follows (Fig. 1): Blade 1 is clamped in fixture 2 which is set on the table 3 . The table reciprocates left and right together with slider 4 and at the same time rocks about axis 5 . To make the rocking motion of the table 3 proportional to the displacement of the slider, gear 6 which rolls along rack 7 is joined to the table. The air-foil is ground by the absras:Lve belt 8 which is directed by rollers and is pressed against the blade by the cam 9 , which is fastened in Card 1/3 S/536/60/000/045/oo6/oo6 Grinding of the Backs .... E073/E335 ram 10 Since the air-foil cross-section varies along its length the cam surface has double curvature. The infeed is accomplished by continuous or intermittent lowering of cam 9 A method is presented in great detail for determining fixture parameters at which a particular air-foil will be successfully ground. On the basis of the method described in the paper, Engineers K.A. F�veyskly and N.M. Tarasova worked out practical instructions for using it under shop conditions. Several types of turbine blades, including cast turbine blades with a considerable twist, are now successfully ground on this machine. Practical experience has shown that after calculating one or two blades, the designer will spend no more than 3-4 hours on determining the parameters of the jigs and over half this time is spent on constructing the cross-sections of the blade. If cross-section plots are already available it is possible to reply in one hour to the question as to whether a given blade can be ground with a given dimenslaii of the rack gear, and what would be the position of the axis of the blade relative to the axis of the rack gear ( 6 , Fig. 1). If the blade cannot Card 2/3 Grinding of the Backs ... S/536/60/000/045/006/006 E073/E335 be ground with the gear of the given dimensions, it is possible to determine additionally in one to two hours the minimum diameter of the rack gear and the minimum length of stroke by means of which the blade can be ground.

It was written jointly by several of the learned institutions of Leningrad.The work deals with the history of two-and-a half centuries. Critics of the book emphasize the fact that this is the first time that, on the basis of Marxist-Leninistic historical research work, the founding of the city--of Len-,.ngrad, its growth, and its development to a center of the militant class-conscious proletariat has been described. Special chapters deal with the part played by St. Petersburg in the history of Russian literature, music, and science. Special interest is caused by the description of the rebuilding of the city after the war. The three volumes of this work have many illustrations and they contain numerous re- Card 1/2 productions of old city plans, drawings, graphs, etc. The 4th A History of Leningrad 30-8-35/37 volume, which will be published withing short, is devoted entirely to the work of reconstruction and the rapid development of the city, as, in view of the vast material, 3 volumes were not found to be sufficient.
