| Research Abstract |
Formation mechanism of deformation-induced layer and mechanism of anomalous reverse transformation induced by shot-peening for Fe-Ni alloys are investigated. In this study, we found that the deformation-induced layer in the Fe-Ni alloys is generated by grain refinement with the formation of shear band due to severe shear deformation. In addition, it was found that the stabilization of austenite due to grain refinement is one of the reasons of the anomalous reverse transformation induced by the shot-peening.
