EFFECT OF THE GRAIN STRUCTURE ON THE EVOLUTION OF MARTENSITIC TRANSFORMATIONS IN A NANOSTRUCTURED TITANIUM NICKELIDE

摘要

Experimental data are presented on the formation of a nanostructure in coarse-grained andsubmicrocrystalline titanium nickelides under severe plastic deformation in the premartensitic state followedby annealing. The effect of the grain size in nano- and submicrocrystalline-structured materials on theevolution of martensitic transformations is considered.
