摘要
探讨了制造单晶铸件所需基本条件之一──制取具有良好性能和晶体取向晶种的即受控晶种的方法。主要对螺旋选晶法受控晶种的制取作了具体阐述。
This paper have studied the making method of crystal seed that is one of basic prerequisite of producing single crystal casting.Controlled crystal seed is of a special crystal direction in which there is a better properties than in that one.In this method,helix selected parts have been used.
