Ti-Ni-BASED ALLOY; WIRE, ELECTRICALLY CONDUCTIVE ACTUATOR, AND TEMPERATURE SENSOR, EACH USING THIS ALLOY; AND METHOD OF PRODUCING A Ti-Ni-BASED ALLOY

摘要

A Ti—Ni-based alloy, which has a torsion angle for Interface I that is a junction plane between habit plane variants of a martensitic phase, of less than 1.00°; a wire, an electrically conductive actuator, and a temperature sensor, each of which uses that alloy; and a method of producing the Ti—Ni-based alloy.
