Abstract
The contribution is devoted to the deformation behaviour analysis of t hree TiNi-type shape memory alloys containing 49.5 at.%Ni(A), 50.4 at. %Ni(B) and 50.8 at.%Ni(C), respectively. The tensile tests were used t o evaluate deformation characteristics of work hardened and annealed a lloys. Both the ,,yield point'' and ,,elastic moduli'' of shape memory alloys are influenced by transformation and/or reorientation plastici ty. The quality of shape memory phenomena is determined by level of wo rk hardening.
