TERNARY Ti-Ni-Cu SHAPE MEMORY ALLOY AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a ternary Ti-Ni-Cu shape memory alloy which is useful as a device for an actuator etc. and has reduced composition dependency and heat treatment dependency, and also to provide its manufacturing method.;SOLUTION: In the method for manufacturing the ternary Ti-Ni-Cu shape memory alloy, an amorphous Ti-Ni-Cu alloy having a composition consisting of, by atom, 44 to 49% Ti, 20 to 30% Cu and the balance Ni with inevitable impurity elements is heated at 500 to 700°C for 100 h to undergo crystallization.;COPYRIGHT: (C)2007,JPO&INPIT
