208 Experimental Research on Recovery Stress of TiNi Shape Memory Alloy

Abstract

The shape memory alloys have been expected from a view point of engineering applications because of its unique mechanical properties. When the shape memory alloy which was deformed at low temperature is heated in the condition with the restriction of strain, the recovery stress occurs by a reverse transformation. In this study, the recovery stress after the torsional loading condition was experimentally investigated in TiNi shape memory alloy tube manufactured by the sintering synthetic method. The obtained results are discussed in this paper.
