Mechanical behavior of nanostructured metals and alloys in the 300–4.2 K temperature interval

Abstract

Abstract Original data of the authors and literature data are presented describing the mechanical behavior of nanostructured metals and alloys at cryogenic temperatures. Bulk ultrafine grained metals and alloys processed by severe plastic deformation through equal channel angular pressing are considered. The mechanical behavior of a number of nanostructured metals and alloys (Cu, Ni, Ti, VT6 and others) were investigated under uniaxial compression and tension at cryogenic temperatures in a wide range of strain-rates. The most important low temperature peculiarities of the nanostructured materials mechanical behavior have been indicated.
