Abstract

It is difficult for the dynamic recrystallization to happen in Steel 26Cr2Ni4MoV, used to manufacture low-pressure steam turbine rotors generally. Static recrystallization was important in the fine crystals generation. Considering this, thermo-torsion method was adopted to investigate the spontaneous austenite recrystallization of steel 26Cr2Ni4MoV. Results show that even minute strain can promote the nucleation and growth of spontaneous austenite recrystallization dramatically, and the increase of temperature can also do so. The discovery can contribute to the realization of controlled forging.
