| Recrystallization temperatures of original austenite and reversed austenite have been investigated in Fe-32%Ni alloy. The former was formed by diffusional transformation, and the latter by diffusionless transformation, At the same levels of deformation degree, the recrystallization temperatures were higher in the original austenite than in the reversed austenite. At the same levels of hardness, however, the recrystallization temperatures were higher in the reversed austenite than those in the original austenite. This is because the cells are smaller and the walls of the cells are thicker in the original austenite than in the reversed austenite, in addition to the difference in vacancy concentration between them, at the same levees of Hardness. |
