N2 - The 300M steel was heated in an electric furnace at the temperatures of 850, 900, 950, 1000, 1050°C, and holding time of 5, 10, 30, 60, 90, 120min. The grain size of austenite was measured by using the linear intercept method on Olympus PMG3 metallographic microscope. The experimental results show that grain size of austenite increases with the increasing of heating temperature and holding time, and the grain growth model of austenite in 300M steel is in the following: d=4.04×106t0.17exp(-(1.32×105/RT)).
