摘　　要：半固态挤压铸造是集半固态加工与挤压铸造为一体,利用半固态浆料的流变性能进行充型并在压力作用下凝固成形的一种材料加工新技术。介绍了直接挤压铸造与间接挤压铸造工艺特点,在此基础上着重介绍了铝合金炮弹壳体的半固态流变挤压铸造工艺。The semi-solid squeeze casting is a new forming process,which is the combination of the squeeze casting and semi-solid forming.In the forming process,based on the excellent rheologic properties of semi-solid slurry,molding is completed,and the solidification is carried on under pressure.The direct and indirect squeeze casting is mainly introduced.Finally,the rheo-squeeze casting process for cannonball shells is mainly introduced.

关 键 词：半固态 直接挤压铸造 间接挤压铸造 工艺特点
