摘　　要：本文研究了中碳钢奥氏体晶粒的生长规律,发现平均晶粒直径D随时间t的变化符合Beck关系式:D=kt^n。根据实验结果,分别求出了n值和奥氏体晶粒生长激活能Q,并对晶粒生长机制进行了讨论。The law of austenite grain growth in medium carbon steel was investigated. It is shown that the variation of the average grain diameter D with the holding time (?) conforms to Beck's law D=kt^(?), the value of n and the activation energy Q for the au(?)tenite grain growth are calculated out according to the experimental results, and the m(?)chacism of austenite grain growth is discussed.
