定向凝固技术及其研究进展

Directional Solidification:the Art and Recent Developments

定向凝固技术是制备一类具有单一取向要求的凝固组织的材料的重要方法,评述了定向凝固技术的发展过程和存在的问题,并报导了在此基础上新近发展起来的新型亚快速及快速定向技术的研究进展。

Directional solidification technique has been used verv widely during the production of many kinds of materials. The development and shortco-mings of traditional directional solidification technologies are reviewed. The recent-ly developed new-type sub-rapid and rapid directional solidification techniques on the base of the traditional directional solidification techniaue are reported.
