对常规铸造Ｐｂ－１７％Ｓｎ合金的固态及半固态挤压进行了研究．结果表明，半固态挤压的挤压抗力远低于固态挤压；在一定的温度范围（１９０～２４５℃）内，进行半固态挤压可获得品质优良的挤压产品。
Solid state and semi-solid extrusion of conventional cast Pb-17% Sn alloys were investigated. The results show that the extrusion resistance of the semi-solid extrusion is much lower than that of the solid extrusion; in the certain temperature range (190 ~ 245 ℃), the semi-solid extrusion can obtain the excellent extrusion products.
