WORKING AND HEAT-TREATING METHOD FOR Fe-Mn-Si BASED SHAPE MEMORY ALLOY ADDED WITH NbC

摘要

PROBLEM TO BE SOLVED: To further improve a shape memory characteristic in an Fe-Mn-Si based shape memory alloy added with NbC, showing a good shape memory characteristic without performing any training.;SOLUTION: After applying rolling-work of 2-70% at 600-800°C to the Fe-Mn- Si based shape memory alloy added with Nb and C under austenite state, an aging treatment is conducted while heating in the temperature range of 400-1,000°C for 1 min to 2 hr.;COPYRIGHT: (C)2003,JPO
