Effect of the Chemical Composition and Structure on the Thermomechanical Behavior of Alloys Based on Titanium Nickelide

Resumo

The effect of microstructure on the special features of the occurrence of shape change in alloy based on titanium nickelide displaying shape memory and superelasticity is studied. It is shown that total realization of these effects depends not only on alloy structure but also on deformation temperature. Temperature dependences are established for critical strains and stresses governing conditions for total initial shape recovery.
