铸造和锻造是早已为人们所熟悉的两种毛坯生产工艺,它们的共同生产特点是生产效率高,但是铸件的表面光洁度差,机械性能低;锻件的工艺过程比较复杂,且形状也比较简单。液态模锻是一种介于铸、锻之间的工艺方法,它克服了铸、锻两种工艺的缺点,同时却 Casting and forging are two well-known rough production techniques. Their co-production features are high production efficiency but poor surface finish of castings and low mechanical properties. The forging process is complicated and the shape is relatively simple. Liquid forging is a process between casting and forging, which overcomes the shortcomings of the two processes of casting and forging, meanwhile
