Elongation to failure in the model of cooperative grain boundary sliding

Autor: A.I. Pshenichnyuk, Oscar A. Kaibyshev

Publikováno v: Materials Science and Engineering: A. :105-108

The macroscopic effect of neck development characterizing the termination of superplasticity has been studied reasoning from certain assumptions on the deformation mechanism at the mesoscopic level. It has been established that characteristics of ult

Structure and damping of nanocrystalline metals and alloys prepared by high plastic deformation techniques

Autor: A.I Pshenichnyuk, Radik R. Mulyukov

Publikováno v: Journal of Alloys and Compounds. 355:26-30

Nanocrystalline (NC) structure materials were formed by severe plastic deformation. In the samples obtained and annealed, the strain amplitude and temperature dependences of the internal friction and tensile strength were measured. An analysis of the

Self-organization of cooperative grain boundary sliding in aluminium tricrystals

Autor: A.I. Pshenichnyuk, Oscar A. Kaibyshev, V. V. Astanin, A.V. Sisanbaev

Publikováno v: Scripta Materialia. 36:117-122

Grain boundary sliding (GBS) being an important mechanism of high temperature deformation of polycrystals acquires a leading role in microcrystalline materials providing a superplasticity effect in them. Self-organization of change (increase) in angl

A computer simulation study of the relation between grain boundary misorientation distribution and crystallographic texture

Autor: A.I. Pshenichnyuk, Alexander P. Zhilyaev, Igor V. Alexandrov, V Yu Gertsman

Publikováno v: Modelling and Simulation in Materials Science and Engineering. 3:149-159

Modelling of two types of crystallographic texture corresponding to cold-rolled material (so-called copper type texture) and to completely recrystallized material (cubic texture) has been performed for hypothetical FCC metals. Orientation distributio

Grain boundary misorientation spectra (GBMS) determined by real ODF in F.C.C.-materials susceptible to annealing twinning

Autor: Alexander P. Zhilyaev, O.V. Mishin, I.V. Aleksandrov, Ruslan Z. Valiev, A.I. Pshenichnyuk, V.Yu. Gertsman

Publikováno v: Acta Metallurgica et Materialia. 41:2657-2665

Four grain boundary misorientation spectra (GBMS) corresponding to four possible types of correlation in orientation of adjacent grains have been calculated by means of computer simulation using orientation distribution function (ODF). The modelling
