DESCRIPTION:Speakers: Vitaliy Pilyugin (M.N. Mikheev Institute of Metal Ph
 ysics of the Ural Branch of the Russian Academy of Sciences (IMP UB RAS))\
 nAfter severe plastic deformation under the high pressure torsion techniqu
 e a number of brittle refractory metals such as Mo\, W\, Re and Ni3Ge inte
 rmetallic compound with L12\nstructure have been investigated. These studi
 es are of great interest\, since the effects of shear deformation under hi
 gh pressure have not been previously studied on these materials. In all ca
 ses the grain refinement caused by dislocations mobility has been observed
 . The Ni3Ge demonstrates the decrease of the degree of the long-range orde
 r after large plastic strain. Synchrotron radiation source has been used i
 n order to determine the level of internal stresses\, crystallite size and
  other parameters of the plastically deformed materials. The models of the
  influence of the mobility of dislocations to crystallite size and fractur
 e surfaces have been considered.\n\n*The reported study was partially fund
 ed by RFBR according to the research project No. 16-03-00182-а and was ca
 rried out within state assignment of FASO of Russia (theme “Deformation
 ” No. 01201463327)*\n\nhttps://indico.inp.nsk.su/event/3/contributions/1
