中文摘要: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。
英文摘要: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 multiplicates, and the yield strength improves.
