- Abstract
The effect of 1 at.% N addition on the shape memory effect of - alloys was investigated. The shape memory effect and superelasticity were observed in -(18-20)-1.0 and -(21-25)-1.0 alloys, respectively. The -23-1.0 alloy exhibits the best superelastic properties with almost perfect recovery and small stress hysteresis among added ternary alloys. The effect of cyclic deformation on the stability of superelasticity was investigated for the -23-1.0 alloy by loading and unloading cyclic tensile tests up to 500 cycles with a constant maximum applied strain of 2.5%. It was confirmed that the stability of superelasticity was improved by the addition of N due to the increase of the critical stress for slip.
