【摘要】 钢材轧后冷却过程中的晶粒长大很大程度上决定着室温组织的晶粒尺寸，定量研究这一晶粒长大规律不仅可建立描述冷却过程中晶粒尺寸变化的模型，以利于计算机对微观组织变化过程的模拟，而且还为进一步的性能预报奠定基础。更多还原

【Abstract】 The grain growth after hot rolling is very important for obtaining final microstructure under room temperature Mathematical models for grain growth after hot rolling have been developed This work is not only helpful for simulation of microstructure evolution but also is a basis for prediction of mechanical properties更多还原
