PROCESS OF MANUFACTURE OF MONOCRYSTALLINE WORKSTOCKS FROM ALLOYS WITH PERITECTIC TRANSFORMATION

摘要

FIELD: technology of manufacture of monocrystalline castings for articles from alloys with peritectic transformation. SUBSTANCE: monocrystalline workstock containing alloy of solid solution crystallizing originally before start of peritectic reaction is used for manufacture of oriented monocrystals from alloys with peritectic transformation. Usage of monocrystalline seed composed of alloy of solid solution crystallizing before peritectic reaction makes it possible to reconstruct orientation of seed in workstock from alloy of peritectic type. EFFECT: enhanced efficiency of process. 1 cl, 1 dwg, 1 tbl
