摘    要:介绍了一种改善金属凝固组织的外场处理新方法一电流处理方法。研究了液态下施加直流电流和脉冲电流对工业纯铝凝固组织的影响。结果表明,该方法可以细化纯铝的凝固组织,使粗大的柱状晶变为细小的等轴晶;处理参数不同,对铝锭的宏观组织细化程度不同。

关 键 词:电流处理  纯铝  凝固组织

Abstract:Electric current modification treating method,a new physical fields process modifying the solidification structure of metals,was introduced.Effects of direct current(DC) and pulse current acting on liquid metal on the solidified structure of pure aluminium were studied.According to experimental results,the macrostructure of aluminium ingot was modified from large grains with columnar crystals to finer grains with equiaxed crystals using the method.The solidification structures could be refined variously under different DC parameters.
Keywords:electric current treating   pure Al   solidified structure
