The Mn content of Fe-17Mn-6Si-0.3C (mass%) shape memory alloy, which was reported to show a superior shape memory effect without being subjected to the training treatment, is decreased by substituting various elements such as Ni, Cr, Cu and Al. The phase transformation behavior accompanied with the shape memory effect is investigated in the alloy with the Mn content from 17 to 9 mass%. The internal friction-temperature curves during cooling and heating indicate that the Ms temperatures of the alloys are below ambient temperature. The shape recovery strain of the alloy shows that there exists a large gap in the shape memory effect between 13 and 11 mass% Mn content. For decreasing the Mn content of the alloy, Ni and Cr are more effective substitutes than Cu and Al. The alloy, which contains Mn more than 13 mass% with Ni and Cr substitutes, exhibits a good shape recovery larger than 2% in strain.
