摘要
采用热模拟变形方法,通过夏比试验研究了锻件内部孔隙结合面的冲击性能恢复规律,为制定合理的锻造工艺,保证锻后冲击等力学性能恢复到初始状态提供了理论依据。
By using the thermal simulation deformation method,the impact property recovery law of the internal pore joint surface of forgings has been studied by Charpy test,which provides a theoretical basis for making a reasonable forging process and ensuring that the impact and other mechanical properties could be restored to the initial state after forging.
