晶粒

The primary phases of Al-10% Cu, Al-20% Cu Al-40% Cu alloy are nearly equiaxed spherical or rose spherical by semi-solid processing. Compared with the coarse arborization of Al-10% Cu, Al-20% Cu Al-40% Cu alloy of conventional casting, the structure of alloy is extremely improved and the appropriate grain size for the engineering application is obtained.

结果表明：利用半固态加工，可以使Al-10%Cu、Al-20%Cu、Al-40% Cu合金的初生相呈近等轴的球状或蔷薇球状，与普通铸造Al-10% Cu、Al-20% Cu、Al-40%Cu合金较粗大的树枝状相比，合金的组织得到显著的改善，达到了工程应用晶粒大小。
