| Research Abstract |
Growth process of butterfly-type martensite is investigated by using Fe-Ni alloy with graded microstructure. The Fe-Ni alloy specimens with graded microstructure are made by the sub-zero treatment under graded temperature or the deformation with graded strain distribution. Characters of martensite depend on not only martensitic transformation temperature but also temperature during its growth. In addition, it is found that the character of martensite is determined by accommodation process for transformation strain under its formation and growth process.
