循环加热对变形碳钢奥氏体晶粒尺寸稳定性的影响

Effect of Cyclic Heating on the Stability of Austenitic Grain Size of Cold Worked Steel

研究了循环加热对变形 6 5钢奥氏体晶粒尺寸稳定性的影响。结果发现 :变形碳钢经预先循环加热处理后 ,可使奥氏体晶粒尺寸稳定性提高 ,预先循环加热次数越多 ,后来加热时奥氏体晶粒尺寸的稳定性越高。

The effect of cyclic heating on the stability of the austenitic grain size of cold worked steel was studied.It was found that cyclic heating can increase the stability of the grain size of cold worked steel,and the more the cyclic heating,the higher the grain size stability.
