The authors present results of research in plastic deformations of welded surfaces and the characteristics of junctions as depend- ent on temperature of metals and methods of deformation. Spot welding and butt; welding were used to ascertain regularities in the welding process. The mechanical characteristics of junctions depending on deformations and temperatures were derived from the butt welding of three different non-ferrous alloys. Recrystalli- zation as a means of increased plasticity of junction was obser- ved in welded Junctions. The interdependability of temperature, plasticity ani3 strength were observed under varying circumstances. Three tables, 7 graphs and 2 drawings. Two Russian references, 1953-54, and 1.

The conclusions reached are the following: 1) The most difficult problem in welding titanium is the daterioral;ion of mechanical properties in the metal at the zone of fusion. 2) The changing ofdh and Y in weld joints accdtding to the temperature is of the same nature as in the base metal. 3) Intensive grain growth in the weld metal and in the adjacent parent metal is observed during welding. 4) The formability of weld joints in # 2 of titanium grades "MM-All emd "IDT-IR 11 was very high and satisfied the produc- tion requirements. 5) The iitructure and the mechanical properties of low-temptra- turecr.,-phase base metal are changing abruptly in the heating- part as dwell as in the cooling-part of the heat cycle; in the temperat-dre interval ofA -phase,& and * are changing only h rA cycle of heating and Cooling, insignificantly. After the t, e ma titanium of all grades possesses lower mechanical properties. 6) For comparing the gas contents of the base metal, a special test %lard 2/3 is recommended. based on heating thin samples to 1300-15000 at 135-4-.1/15 TITLE: Weldability of Titanium (Issledovaniye evarivayemoati titan&). different speeds. The criterion for evaluation in this test is this critical heating speed at which formation of bulges and pores 4.8 Dbaerved in the metal. 7) The choice of welding technology is to be based on keeping the metil a short time in the A-phaae temperature of intensive grain growth, and on slowing down the cooling in the interval of P-,oa conversion.

On certain relations governing creep of copper and alliminJilm (Cont.) 119 (the ree limit, the toughness and the coefficient of hardencino were determined for various conditions of deform- ation and preliminary work hardening of the specimens. It is shown that the mecbanical propc3:ties of polycrystalline copper and aliuainium depend on the grain-size of the metal and, with inC3.,easing dispersion, the creep limit, the tough- ness and the coefficient of hardening and also the elastic part of the doformation will increase. The influence of the temperatuie on the kinetics of the plastic deformation of the metal was also studied; with i-nereasing temperature an imensive process of relaxation takes place in the deformed specimens, as a result of which the toughness, the yield point and the work hardening coefficient decrease. In addition to intragranular slip flow in the inter-crystalline layer takes place during the process of creep of the metal. The relative importance of the viscous flow increases with increasing temperatuie. 10 references, 8 of which are Russian. Moscow State University imeni M.V. lionLonosov. Reed.

The adsorption effect fe,cilitating deformation of the metals investigated was estimated from the increase in the rate of flow of the specimens on &,training in the active, as compared with a non-aetive '. medivm.. The rate of flow was determiniDd at equal degrees of elongation of the specimens, as the strength properties of the metal depend very largely on the degree of deformation. Measurements carried out in solutiona of alcohols in non-polar kerosene at concentrations of from 0.060 mol/l. and abolre ha,le shown that the rate of flow of both copper and aluminium, tpecimens depends on the concentriLticn of the surface-activer medium in the solution.

TITLE: On the Influence of Oxide Films and of an Adsorption-Active Medium on the Creep of a Copper Wire (0 vliyanii okisnykh plenok i adsorbtsionno-aktivnoy sredy na polzuchest' mednoy provoloki) PERIODICAL: Doklady Akademii nauk SSSR, 1950, Vol 122, 41ir 4, pp 643-645 (USSR) ABSTRACT: The exp:.anation of the influence of thin oxide films on the mechanical properties of polycrystals is very important. The authors found out that the deformation of a polyerystalline copper wire is impeded 4'L it is carried out in water. The samples - wires of electrolytic copper of 0,5 mm diameter - were tempered in order to get the grain dimensions (- 0,1 mm) necessaxy for the optimum observation of the adsorption effect.

The curve for tho creep in water is noticeably lower than the cur-ire for the creep in air. If the samples are immersed in wate.v, they are covered by a reddish oxide film the thick- ness of which amounts to some hundreds of Xnlrstrbm. The forma- tion of this ixide film is caused, apparently, by thu lis- solution of air oxyCen 'in water. The above-discussed strengthen- ing of the wires takes'place only in the presenco of oxide films. Surface-active substances (for instance, butyl alcohol) adsorbed on the metal from an aqueous medium, increase the creep velocity with respect to the creep in water and in air. According to the results of this paper, thin oxide films may exercise considerable influence on the mechanical properties of monoorystals and also of polycrystalline specimens. The diminishing of the creep velocity by the influence of thin oxide films on the surface of metals may be explained on the basis of dislocation hypotheses. The authors thank Ye. D. Shchukin for his useful advice. There are 1 figure, I table, Card 2/3 and 11 references, 7 of uhich are Soviet.

If the power spectrum is symmetrical with respect to a centre frequency wo, and the bandwidth of the spectrwn AW 1~30) the process can be represented ast ~ (t) = A(t) cos Cw,t + A~'k' t)] - (2) where AW is a slowly changing envelope of the quasi- harmonic noise e,(t), The correlation coefficient R of 't(t) also contains an envelope, as can be seen from Eq (3). The two-dimensional probabilit density distribution of the quantities A, :: A(J and A2 = A(t+T) Card 1/1+ is in the form of Eq (4), where Io is the Bessel function of the zero order. It is assumed that tho SOV/109- - -4-3-11+/38 Inertialess Transformations of the Envelope of Quasi-Harmonic Fluctuations envelope undergoes the following inertialess transfor- mations: q .1 = G, (Al) q2 = G2(A2) (5) In various problems it is necessary to evaluate the 2nd moment of these transformations; this is defined bys 001CP
