| Abstract: | Pipe joints made of the Fe 28Mn 4Si(adding Mg)shape memory alloy(SMA) seamless steel tube has been studied in this paper.When the inner radus of steel tube is expanded by 5.6%,the strain recovery ratio will be 38.68%,and this strain recovery ratio is enough for using as pipe joints.The pulling test and leakage test results show that the pipe joints have high joint strength and good leakproofness. |
