Abstract
The aim of work is to study the effect of microstructure transformation from coarse-grained to submicrocrystalline structure in samples during warm isothermal (723K) abc-pressing on inelastic properties of Ti49.8Ni50.2(at.%) alloys. Experimental dependences of superelasticity (SE), shape memory effect (SME), the total recovered inelastic strain (SE+SME) and plastic strain versus the total shear pre-strain under torsion was obtained. It is shown that the total inelastic strain are 18% in the initial specimens, 15.8% in specimens after abc-pressing with the true strain 0.62 and monotonically increases up to 18.3% while true strain increases up to 8.44.
