摘要
回顾了传统定向凝固的发展概况 ,指出了其存在的弊端 ,介绍了国内在新型定向凝固技术方面的发展 ,综述了国内近些年在电场作用、对流 (包括自然对流和强制对流 )、变速生长以及熔体过热等条件下的最新定向凝固试验研究进展 。
Developing survey of traditional unidirectional solidification was reviewed and its shortcomings were presented. Development of novel technologies in unidirectional solidification was introduced at home. Latest progress in unidirectional solidification research was surveyed at home under the conditions of electric field, natural and forced convections, varying growth rate and melt superheating. The developing tendency of unidirectional solidification was predicted.
