The following results were provided by this research.(1) The Ti-Ni-Zr actuators are fabricated by centrifugal casting using P/M ingot. (2) The actuators same as a model were made by casting. (3) The actuator worked in 130 degrees Celsius. (4) I clarified the shape memory characteristic of casting specimens. (5) It was only for it once, the reverse martensitic transformation temperature rose 200 degrees Celsius by the introduction of the pre-strain.

本研究提供了以下结果。(1)采用粉末冶金铸锭离心铸造法制备了Ti-Ni-Zr驱动器。(2)采用铸造法制作了与模型相同的驱动器。(3)致动器在130摄氏度下工作。(4)阐明了铸造试样的形状记忆特性。(5)仅对它一次，通过引入预应变，逆马氏体相变温度上升了200摄氏度。
