工业连续铸造的铝及铝合金铸锭,同其他任何金属及合金铸锭一样,其断面宏观组织也是由三层(细晶粒的表层,中间的柱状晶层,中心的等轴晶层)组成的。不过,由于合金的性质,也就是成分的不同,以及结晶条件的不
Industrial continuous casting of aluminum and aluminum ingot, like any other metal and alloy ingot, the macrostructure of which is also composed of three layers (fine grain surface, middle columnar layer, central equiaxed layer) of. However, due to the nature of the alloy, that is, the different components, as well as the crystallization conditions are not
