本文报导利用内耗方法研究高温回火过程中铁素体晶粒长大过程.实验指出了回火过程中铁素体晶粒长大和碳扩散峰升高的关系.用内耗方法计算出了晶粒长大的激活能,讨论了回火铁素体晶粒和亚晶粒的概念问题.
In this paper, the internal friction method is used to study the ferrite grain growth during high temperature tempering.The relationship between grain growth and carbon diffusion peak during tempering is pointed out.The grain growth The activation energy is discussed and the conception of tempering ferrite grains and subgrains is discussed.
