摘要
评述了近年来脉冲电流细化金属凝固组织方面的研究进展,总结探讨了脉冲电流影响金属凝固组织机理的不同观点。指出脉冲电流细化金属凝固组织机理尚存争论,但是技术已经比较成熟,已具备工业应用的基本条件。
The progress status of researches on pulse electric current refinement of solidification structures of metals was reviewed. The viewpoints on the solidification structure refining mechanism of pulse current was summarized and discussed. It was pointed out that there are still disagreements on the electric pulse refining mechanism, however the technique has been quite mature, and has possesses basic conditions for application in industry production.
