Research Abstract

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.
