摘要
主要介绍了难熔金属W,Mo,Ta,Nb及其合金单晶的制备技术,单晶的发展现状,并对单晶制备技术和单晶材料的发展方向提出了一些合理化建议。
The preparation technology and development on the single crystals of refractory metals of their alloys were introduced in this paper. Some suggestions have been given on the R&D prospects of processing technology for the single crystals of refractory alloys to enhance the high temperature creep resistance.
