| Research Abstract |
The effect of dual phase region deformation on the dynamic ferrite transformation was investigated by quantitatively measuring the bulk textures of in situ hot-compressed samples through using a domestic angle dispersive neutron diffractometer and an oversea time-of-flight neutron diffractometer, and the relative slow dynamic ferrite transformation in lower temperature dual phase region was found due to the occurrence of dynamic ferrite recrystallization during heterogeneous plastic deformation. The texture memory phenomenon during the step-by-step heating and cooling of a cold compressed low alloy steel sample is related to the phase strains during phase transformation rather than the deformation stored energy obtained in the initial sample.
