PURPOSE:To produce a shape memory alloy having an excellent shape memory effect at low cost, by adding trace amounts of N or furthermore adding specific elements to an Fe-Mn alloy contg. specific amount of Mn. CONSTITUTION:0.03-0.30% N, by weight, is incorporated into the Fe-Mn alloy in which the Mn content is subjected to componental regulation to 15.0-30.0%, or furthermore one or more kinds selected from plural groups among <15% Cr and <15% Ni, <6% Si and <6% Co or <0.5% C and <0.5% Al are incorporated thereto. The Fe-Mn shape memory alloy having >=0.5 shape recovery rate and having the excellent shape memory effect can be obtd. at low cost. |
