METHOD OF PRODUCTION OF ORIENTED SINGLE-CRYSTAL BLANKS FROM ALLOYS WITH PERITECTIC TRANSFORMATION Russian patent published in 1997 - IPC

Abstract RU 2084561 C1

FIELD: foundry; production of single-crystal castings for products from alloys with peritectic transformation. SUBSTANCE: use is made of a single-crystal blank composed of an alloy of solid solution primarily crystallized up to the beginning of peritectic reaction. Use of a single-crystal seed composed of solid solution alloy crystallized up to peritectic reaction makes it possible to reproduce orientation of the seed in the blank from alloy of the peritectic type. EFFECT: facilitated procedure. 1 tbl
