Study on Pseudoelasticity in Antiferromagnetic MnFe(Cu) Alloys

The pseudoelasticity of antiferromagnetic MnFe(Cu) alloy was studied by using compression test.The results show that the samples used in this test present preudoelasitic,and with a certain degree of self-recovery capability.The pseudoelasiticity of Mn51Fe49 and Mn80Fe15Cu5 alloys increases with the target load increasing.In Mn85Fe10Cu5 alloy,when the loading frequency is low,the pseudoelasticity increases with the increase of loading frequency;when the loading frequency continues to increase,the pseudoelasticity of the alloy drops.
