Abstract
Plastic zone with equivalent plastic strain ε above 0.02 PZ0.02 and that above 0.12 PZ0.12 in 304 stainless steel small punch specimen loaded at RT and 77K to various level to fracture were measured by the recrystallization technique. Martensite transformation was also checked magnetically. It is found that the behaviour of both PZ0.02 and PZ 0.12 is at first stretching mode, then stretching and bending mode and then stretching mode. PZ0.02 and PZ0.12 propagated to the clamped region of the specimen.
