Information × Registration Number 0200U003475, 0197U016509 , R & D reports Title The investigation of relaxation effects which ecompany the elastic and plastic deformation of status solidies with various defect structure popup.stage_title Head Sirenko A.F., Registration Date 15-05-2000 Organization Kharkov National University named after V.N. Karazin popup.description2 The regularities of rotational mode appearance and development in two-dimensional aluminium and copper polycrystals with the various contents of triple grain boundary junctions have been studied. The features of the stress state relaxation in the triple grain boundary junction areas in two-dimensional polycrystals with fcc-lattice depending on grain boundary types and triple junction density in samples have been researched. The influence of the regularities of rotational effects appearance and development on failure character of two-dimensional aluminium and copper polycrystals is studied. The peculiarities of the creep and unelastic aftereffect in the Pb-62% Sn alloy depending on the duration of natural aging of the alloy have been researched. The internal friction in the industrial of the Al-Cu-Mg system alloy have been researched. The peculiarities of changing of the Pb-62% Sn alloys deformed under the creep conditions at the optimal for superplasticity conditions have been studied.
