| Abstract: | This paper researches for the influence of holding time on austenite grain growth of 12%Cr steel from 1 000℃ to 1 250℃.On experimental studies,we acquire the austenite grain growth law in the high temperature,establish the dynamic model of grain growth,and compare the simulating values and experimental values.The comparing result shows that the dynamic model can forecast the grain growth law with higher accuracy. |
