摘要：

Dynamic transformation (DT) of deformed austenite to ferrite at temperatures above A(e3) occurs during a multi-step hot torsion test of a Nb-bearing medium manganese steel. In torsion tested specimens, equiaxed grains are dispersed within a martensite matrix, and the average grain size is less than 1 mu m. Electron back-scattering diffraction results confirm that most of the equiaxed grains are recrystallized ferrite, and there is a small fraction of retained austenite.
