Recovery Stress Associated with the R-Phase Transformation in TiNi Shape Memory Alloy. Properties under Constant Residual Strain.

Hisaaki Tobushi; Kimio Kimura; Takayuki Sawada; Takeharu Hattori

The recovery stress associated with the R-phase transformation in TiNi shape memory alloy was investigated experimentally concerning constant residual strain. The results are summarized as follows. ( 1 ) The recovery stress in the heating process is larger than the R-phase transformation stress in the loading process at low temperature. ( 2 ) In the heating process, the recovery stress occurs at about 320 K and takes a maximum value at about 335 K. The recovery stress increases along the reverse transformation line on the stress-temperature plane. ( 3 ) The higher the shape memory processing temperature, the larger is the recovery stress. ( 4 ) The larger the maximum strain at low temperature, the larger is the recovery stress.
