Deformation induced ferrite transformation related to microstructure refinement has attracted wide attention. However, the in situ crystallographic evolution studies have not been carried out. In this paper, the deformation induced ferrite transformation at two different strain rates was carried out to compare that during isothermal holding without deformation and the effects of hot deformation and strain rate on the dynamic transformation evolution was investigated. The neutron diffraction experiments confirmed that the deformation induced ferrite transformations could appear not only in the austenite region, but also in the austenite-ferrite dual phase region. It was found that the low temperature deformation was more effective than the high temperature to promote the ferrite transformation until a critical strain, and then the accelerating effect was weakened due to the increment of austenite carbon concentration and the appearance of ferrite dynamic recrystallization.

The dynamic recrystallization evolution of two martensite steels 17Ni-0.2C and 2Mn-0.2C during warm compression were investigated by neutron diffraction. For 17Ni-0.2C, the warm compression at 773K promoted the austenite precipitation from the martensite matrix. The austenite deformation texture gradually increased. For the ferrite, the deformation texture component first increased and then become stable or weak to a certain extent because of the onset of recrystallization texture component. For 2Mn-0.2C, the proper tempering treatment at 873K led to the occurrence of static recovery of martensite to a certain extent and the precipitation of cementite. The onset of ferrite dynamic recrystallization in 2Mn-0.2C was at a higher nominal strain than that in 17Ni-0.2C. It was believed that this difference was mostly related to the different volume fraction of hard second phase.
