研究了SWRH82B钢在高温多道次高变形速率下再结晶的规律.结果表明,随轧制道次的增加,晶粒尺寸逐渐减小,索氏体的含量不断增加,屈服强度逐渐提高.

The re-crystallization rule of SWRH82B steel at high-temperature,more rolling times and high deformation rate was studied.The results indicate that,with the increase of rolling times,the grain size becomes smaller,the content of sorbite multiplieates,and the yield strength improves.
