초록

Shape memory alloy springs have been fabricated and annealed at $400^{\circ}C$, $450^{\circ}C$ and $500^{\circ}C$ in atmosphere and in nitrogen gas. The optimal heat treatment condition in view of maximum generated force has been decided by the iso-thermal test with variation of annealing condition. Experimental results show that the heat treatment with high temperature in nitrogen gas is desirable for high generated force and can be used for the design of shape memory alloy springs.
