Abstract

Nanocrystalline (NC) Ti_49.4Ni_50.6 alloy in the shape of a disc 20 mm in diameter has been successfully produced using high pressure torsion (HPT). The features of microstructure, martensitic transformation and deformation behavior of the NC alloy have been studied in details. The effects of the grain size on mechanical and functional properties of the alloy are discussed.
