　In this study, the aim is to investigate the relation ship between the strain rate and the effect to the shape memory effect, which is called the training effect on the Fe-SMA. in the study, Fe-28Mn-6Si-5Cr alloy which is a kind of SMA is used. In addition, by referencing the description given by Awaji material and other researches, the training process is studied at tensile and compressive condition. During the test, different loading and unloading strain rate is used. After that, to verify the effect to the SME, the verification test is conducted with a constant initial strain and strain rate. Some of the result is shown as follow.
