Shape Memory Effects in an Fe14Mn6Si9Cr5Ni Alloy for Joining Pipe

The shape memory effect (SME) of an Fe14Mn6Si9Cr5Ni alloy has been studied, and resulted to be the best for joining pipe. Training can improve the SME of the alloy. Fe14Mn6Si9Cr5Ni alloy shows good creep and stress relaxation resistance. Its corrosion resistance in alkaline solution is 4-5 times better than that of 304 and 316 stainless steels. The tensile force of 20 KN and sealing pressure of 6 MPa can satisfy usual requirements for joining pipe in general industrial applications.
