Method of processing and heat-treating NbC-added Fe-Mn-Si-based shape memory alloy

摘要

A NbC-added Fe—Mn—Si-based shape memory alloy is provided, showing a shape memory property even if a special treatment such as training is not performed.;A Fe—Mn—Si-based shape memory alloy containing Nb and C is rolled by 10 to 30% in a temperature range of 500 to 800° C. under austenite condition, then, subjected to an aging treatment by heating in a temperature range of 400 to 1000° C. for 1 minute to 2 hours.
