A total 450 papers dealing with the achievements in the field of hydrology since the begin- ning of Soviet rule were delivered to the plenary sessions. Over 90 papers were devoted to prognoses and calculations of the flow. About 40 papers were presented by invited guests. Special attention was paid to problems of sub-soil water utilization and hydrological engineering. ASSOCIATIONs Institut geografii AN SSSR-Moskva (Institute of Geography of the AS USSR-Moscow) 1.

In the recrystallized state, the alloys exhibit one maximum at 300o, a condition indicati%e of relaxation along the grain boundaries. The maximum IF point, corresponding to 150o arld situated in the region of recrystdIlization (R) temperatures, is go%erned by the viscous behavior of the slip lines. In the light of dislocation theory, this maximum is attributable to the dispersion of energy connected with the mot-on of dis- locations (D) under the influence of external stresses.

A new maximum was detected, which is attributed to the diffusion of magnesium, and it is shov,,n that this maxi- Mum is displaced t6 higher temperatures and that the acti- vation energy of magnesium diffusion increases vith increasing concentration of magnesium in solid solution. The displacement of the maximum of internal friction is explained by the complication of the elementary act of di- ffusion as a result of the non-uniform distribution of magnesium in the deformed solid solution and formation of magnesium atom clouds around non-uniformities of the crystal lattice. The authors considered the study of the diffusion in deformed aluminium-magnesium alloys of interest since, with increasing magnesium concentration, the inter-atomic bond forces do not change but considerable distortions occur in the crystal lattice which are caused by the magnesium atoms. The specimens used were 0.9 mm dia. and 300 mm long li> Internal friction of deformed alloys of alwainium V11th magnesium. (Gont.) wire deformed at room temperature by drawing with a reduction of 90%. The internal friction was measured 0in the case of slow furnace heating at a rate of about 50 C/hr. The measured temperature dependence of the internal friction is plotted in the Graphs, Figs. 1 - 5; Fig. 6 gives the depend- ence of the position of the maximum of internal friction as a function of the magnesium content; Fig. 7 Cives the depend- ence of the recrystallisation temperature on the magnesium concentration. The graph, Fig. 8, shows the dependence of the activation energy of diffusion of magnesium as a function of the magnesium concentration in the solid solution. The temperature dependence of internal friction due to distortions in ihe crystal lattice, which are caused by the plastic deformation, do not suffer appreciable changes during trans- ition through the recrystallisation temperature, and this indicates that the maximum of internal kriction is caused by such distortions in the crystal lattice which do not cease during recrystallisation. It was found that an increased concentration of magnesium also changes the curve of internal friction and this leads to the assumption that the quantity of the most mobile distortions decreases with increasing magnesium con-tent. 8 graphs, 18 references, 10 of which are Russian. - Institute of Metal Physics, Ural Branch,Ac.Sc.

PERIODICAL: "Fizika Metallov i Netallovedenive" (Physics of Metals and Netaalurgy)v Vol.,LVP JNo.Zr_M9 PP-383-384 (USSR) - ABSTBACT: The temperature dependence was investigated of the inter- nal friction of recrystallised m-solid solutions of ft and Al by means of low frequency torsional oscillations. The investigated alloys contained 0.01, 0.05, 0.5, 1 and 2 wt.% of Ng. For obtaining the necessary grain size all the alloys were annealed at various temperatures with an approx- imately equal heating speed. The measurements have shown that for low 14g concentrations (0.01 and 0.05%) the curves have only a single maximum at about 300 C and this is attri- buted to the tough properties of the grain boundaries in the metal manifesting themselves. The dependence of this -Winum on the ain size,is similar to that observed by leg T'.8. Phys Ire V. 1947t7lp533; 1947972941). Alloys containing O.j and 1% Ng show an additional maximum at 0Lrd 1/3 about,380 Cp whereby at 2% Mg the second maximum ceases to exist. Izr this case the influence of the grain size on the internal friction also has a more complicated character. Internal friction in recry-stallised aluminium-magnesium alloys. (Cont'.) 126-2-~0/30 Earlier the existence of two maxima was observed on re- crystallised Au of 99'.998% parity and this was explained by various stages of recrystallisation (Mash D.R. and Hall, L.D Journ. of Metalsv 1953, 5, 937). However, data obt;ined by the author of this paper indicates that the occurrence of a second maxim, should be attributed to re- laxation stresses along the boundaries of the blocks of the structitral mosaic. It is known from literary sources that alloying with Al leads to an intensive decrease of the block dimensions after deformation and also of the speed of growth of the blocks during subsequent heating. Thus,if Al is alloyed with Ng it is possible to obtain in the re- crystallised material a large quantity of boundaries of mosaic blocks which give a maximum on the internal friction curve. Regarding the influence of the Mg concentration on the investigated processes of stress relaxationp the follow- ing can be stated: reduction of the level of the maximm of internal friction along the grain boundaries was observed; cud 2/ 3 in an alloy containing 0.5% V9 this maximum drops faster with increasing grain sizes than in the case of 0.01% Mg content; the second maximu ceases to exist on increasing Internal friction in recrystallised alumizLium-magnesium alloys-.

Such a combination of properties permits studyin6 in the pure form the influence of crystal lattice distortions on the mechanical properties. The authors investigated the temnerature dependence of the yield point and the ultimate strength of pure alwainium (containing about 0.01% Mg, 0.0017% Fe, 0.0014% Si, 0.0011~16' Gu) and its maGnesium alloys (0.05, 0.1, 0.3, 0-~ and 1% Mg) in the teuperature range betvteen 8Q and 709 K for_4idely differing deformation speeds (6.4-10-2. 2-10 ") 2-10 ). It -.-.as established that for pure aluminium the temperature depend8nce of the yield point in the temperature range up to 500 K is determined fundamentally by a chanGe in the interatomic bond forces. At elevated temperatures a more pronounced dependence was detected of the yield point on the tei,,iperature,which is apparently due to defoxmations Card along the brain boundaries.

Since such a peak is absent in monocrystals of pure metals, its appearance is ascribed to relaxation at the grain boundaries.l'iWhen impurities are introduced into pure metals, an additional internal friction peak appears; it is known as an impurity peak. From the systematic investigations of this impurity peakj carried out by several workers (Ref I to 5), the authors draw the following general conclusions: (1) Even small amounts of impurity (0.03 atomic S. Ref 3) may produce an impurity peak of internal friction. (2) On increase of the impurity concentration the impurity- peak height generally rises but in certain alloys it reaches a maximum and then falls or even disappears completely (Ref 6) at higher impurity concentrations. Card 1/3 (3) The activation energy of relaxation processes 67657 SOVI 126- 8 -6-4/24 The Mechanism of Formation of an Impurity Peak of Internal Friction responsible for the impurity peak is close to the activation energy of diffusion of atoms, provided the impurity concentration is sufficiently great. (4) With increase of the impurity concentration the internal friction peak due to relaxation at the grain boundaries (observed in pure polycrystals) is depressed and may disappear altogether (Ref 1 to 3, 6). (5) The impurity peak is found only in polycrystals and not in monocrystals and consequently, just like the peak observed in pure polycrystals, it is due to processes occurring at the grain boundaries. (6) The magnitude of the impurity peak is only slightly affected by the change in the mean grain dimensions (it falls gradually with increase of these dimensions; Ref 3 and 6). In contrast, the relaxation time related to the impurity peak depends strongly on the mean grain dimensions, rising rapidly with increase of the latter. The experimental observations sunmiarized in the above six points can be explained as follows. Impurities are concentrated predominantly at the grain boundaries because Card 2/3 the energy of distortion by an impurity atom is lower at I/ 67657 5OV/126-8-6-4/24 The Mechanism of Formation of an Impurity Peak of Internal Friction the grain boundary than inside the grain. Elastic deformation which alters this distortion energy would either favour or obstruct accumulation of impurity atoms at the grain boundaries. Consequently if such deformation is varied periodically the impurity atom concentration at the grain boundaries will also vary periodically. If elastic deformation alternates sufficiently rapidly the changes of the impurity concentration will not manage to follow elastic deformation and this will, of course, lead to dissipation of elastic energy, ie to an impurity peak at appropriate frequencies. The authors discuss this mechanism mathematically and show that it explains satisfactorily the experimental data summarized in the points (1) to (6) above. The paper is entirely theoretical.

The results of many investigations (Ref.1 to 10) 'have shown that internal friction measurements provide a tool which: .is eminently suitable for studying the effects of various treatments on the properties of grain boundaries. The object of the present investigation was to study how the temperature- dependence of internal friction is affected by the variation of the conditions during annealing. In the first series of experiments, specimens of ure aluminium A15000 (AVOOO), cold-rolled to 90% reduction of arCea,,-were Used. (Tne~,Sepecimen was heated to 4000C at a rate of 10 /aii~; the other wals% placed in the furnace at 4000C,' .Card 1/6 -7 S/520/59/000/022/014/021 The Effect of Recrystallization ... E193/E483 as a result of which it attained the annealing temperature at a rate of 1000C/min. Both specimens were held at 4000C for 15 min, after which they were furnace-cooled to room temperature. Both treatments ensured full recrystallization of the metal and growth of sufficiently large grains. The results or internal friction measurements, carried out on these pecimens, are reproduced in ,; Fig.1, where internal friction W is plotted against the test temperature, Curves 1 and 2 relating to specimens that had undergone, respectively, slow and rapid recrystallization. It will be seen that'although in both cases tile internal friction peak occurred at the same temperature, its magnitude was 1.5 times larger'in the rapidly recrystallized specimen. Similar results werejobtained for specimens, preliminarily cold-worked to 70','* reduction iri area. On the other hand, no increase in the internal friction peak was observed in a specimen that had been rapidly recrystallized at 500*C (see Curve 3, Fig.1). Macro- and microscopic examination of the specimens revealed no structural differences, the average grain size in all cases being 0.15 to 0.17 mm. In order to check whether the effect observed was not caused by the presence of impurities (().0()17';'- Fe, 0.0015% Si, 0.001% Cu, 0.01% Mg), the experiments Card 2/6 S/520/59/000/022/014/021 The Effect of Recrystallization ... E193/E483 were repeated on the same material, re-melted in vacuum. Since identical results were obtained, it was concluded that the observed increase in the magnitude of internal friction peak was due solely to increased rate of recrystallization. In the next series of experiments, the effect of isothermal treatment, applied after rapid recrystallization, was studied. Specimens of vacuum re-melted aluminium were rapidly heated to 4100C and were then hold at 3750C for periods ranging to 12.5 h. With increasing duration of this treatment the internal friction peak decreased, but even after 12.5 h at 3750C, it did not reach the low level of internal friction of slowly recrystallized specimens. This effect is illustEited in Fig.3, where the magnitude of the internal friction peak Q1naX* is plotted against time (hours) at 3750C. In the final stage of the investigation, the effect of the rate of recrystallization on internal friction'peak of cold-worked specimens of aluminium alloys, containing 0.5 and 1% Mg, was studied. It was found that in the case of these a;loys the magnitude of the internal friction peak was practically unaffected by the recrystalLization rate. One of the possible explanations of the effect observed is based on the assumption that the rate of Card 3/6 S/520/59/()00/022/014/021 The Effect of Recrystallization ... E193/1',1183 heating during annealing affects the texture of' a recrystallized Inetal. The existence, form and degree of texture should be reflected in the energy state of atoms on the grain boundaries and should, consequently, affect the magnitude of internal friction in this region. This view is supported by the results obtained recently by Ye.I.Krupnikova-Perlina and D.T.Layner Olef.14), who have shown that the degree of texture i.4 highly dependent, on the annealing time and temperature. An alternative explanation is based on the possible effect of the annealing conditions on the degree of enrichment of the grain boun0aries by the imptirity atoins. 1t could be assumed that after rapid rocrystallization, 'the impurity atoins concentrate at the newly fori-,ied grain boundaries pot at once but gradually, while the specimen is held at a given temperature. This theory would explain the ab.-sonce of the increase i,~n the magnitude of the internal friction peak in alloyed alut~iniuni in which the concentration of impurity atoms at the grain boundaries is relatively high, irrespective of the rate of recrystallization; it would also explain the effect of isothermal treatment on the magnitude of the internal friction peal, (see Fig.-)), since this treat,~ient, accompanied by continuous diffusion of the impurity Card 4/6 S/520/59/000/022/014/021 The Effect of Recrystallization E193/E483 atoms, would tend ultimately to increase their concentration at the grain boundaries. The explanation favoured by the pre3ent author is that after rapid recirystallization, the grain-boundary regions are characterized by a low degree of perfection of the crystal structure and contain a large number of lattice defects. After a long isothermal treatment, or after slow heating to the recrystallization temperature, the metal in the grain-boundary rogions is brought nearer to the equilibrium condition, as a result of' which the internal friction at the grain boundaries decreases. The experimental evidence available at present.is not sufficient to decide which of the hypotheses discussed above is the most Ii 'kely explanation to the effect studded by the present author.

The aluminium C contained Fe - 0.0017%, Cu - 0.001%, Si - 0.0015% and Mg - 0.01%. The measurements were carried out on 0.9 mm dia specimens using frequencies of 1.5 and 0.5 Cps. All the samples were preliminarily deformed to 90% and recrystallized with a slow heating rate of 10C per min up to 4oo to 430*C and holding at this temperature. The maximum of the curve moves to a higher temperature with decrease in purity. The results show that with increase in purity, the content of impurities at the grain boundaries decreases. This decrease cannot be connected with the thermal treatment of the samples as they were all treated alike.

The first is attributed to non- equilibrium changes in the concentration of vacancies in the body of the grain, whilst the latter in associated with similar changes in the concentration of vacancies at grain boundaries. The authors support the view that the rapid increase in internal friction at high temperatures can be associated with vacancies whose number in known to increase very rapidly with increasing temperature. They assume that the Internal friction background is due to non-equilibrium changes in the number of vacancies during periodic deformation of the specimen. Thus, it is well known that the concentration of vacancies in a metal to a function of state. While the specimen is tested for internal friction. the applied periodic deformation changes its state and therefore there should Card 1/4 High-temperature internal friction ... 5/126/61/012/oo4/oi4/021 2032/Z535 be an attendant periodic change in the number of vacancies. However, the process of change in the number of vacancies takes a certain time (relaxation time) introducing a tag between this process and the applied deformation. Thus, the deformation will be a non-equilibrium one and will give rise to dissipation of the energy of mechanical vibrations, i.e. to internal friction. Standard thermodynamic calculations lead the present authors to the conclusion that the non-equilibrium change in the concentration of vacancies during periodic deformation of the specimen will give rise to a very nearly exponential increase in the internal friction, beginning at a temperature at which the number of vacancies becomes 'Sufficiently large and will not result in an internal friction peak within a certain temperature range. This in consistent with the known behaviour of the internal friction background in metals at high temperatures. On the other hand, the peak of internal friction at grain boundaries is associated with changes in the concentration of vacancies at these boundaries. Thus. during periodic deformation the grain boundaries will absorb vacancies from the body of the grain and partially re-eject them Into the Card 2/4 High-temperature internal friction ... 5/126/61/012/004/014/021 E032/19535 body, depending on the nature and period of deformation. Any lag between the variation in the concentration of vacancies and the periodic deformation will give rise to damping of the vibrations, i.e. to internal friction. This mechanism to identical to that put forward by the present authors in Ref.13 (FM, 1959. 8. 829) for elucidating the nature of the impurity peak of internal friction at grain boundaries, the only difference being that in the present case the impurities am replaced by the vacancies. Again, thermodynamic calculations involving the relaxation time of elastic moduli are used to develop quantitative relationships for this effect. rt is shown that the relaxation time has a much stronger dependence an the numb;r of grains per unit of volume than the height of the peak (q- /3 an compared with 41/3 ). This in in qualitative agreement with the measurements of T. S. Ke (Ref.28: Phys.Rev., 1947, 72, 41) on aluminium and those of W. Roster at al. (Ref.6t Ze.

Impact strength was investigated at temperatures of from +20 to -60*C. The specimens were also elect rown lc ro scopically examined with the aid of an UENIV-100 inicroscope and the phase composition of the Isolated particles trapped by the carbon replica was determined %%ith i the aid of electron diffraction patterns. Thormokinctic diagrams were plotted to elucidate the effect of V and N on the kinetics of austenite decomposition, this decomposition itself being in- vestigated by the dilatometric method at 950*C. Findings: the hardness and ultimate strength and yield point of aU the Investigated stools Increase with increase in normalizing temperature,, and this Inc rease is the higher the greater the V content of the steel is (up to 0. 10-0. 2 0% V). As the normalizing temperature increases, the amount of decomposition products increases, this being due to the dissolution of vanadium nitrides in the austenIte and increase in its stabl- lity on cooling. Treatment of 15G2 steel with N and V markedly increases the stability of supor-~ cooled au;tcnitc and reduces Its transformation temperature both in the pearlitic and interme- diate regions. Electrorunicroscopic and electron-diffraction-pattern examination shows that i following normalizing from 920*C comparatively large undissolved particles of vanadium ni- trides remain in the steel, whereas at normalizing from higher temperatures these particles got dissolved in the austenite and segregate in flne-disporse form on cooling; such a segrega- Card 2/3 ACC 14-7t: tion enhances the mici-ohardiiess of forritc to 175 from 1.35 l(g/mm2 . Thus, the increase in the strength of 15G2AF steel following its nornializing from 1050*C is attributable to the segrega- tion of fine-disperse Vanadium nitrides in the structure of this steel as well as to the presence of decomposition products in the intermediate stage.
