Effects of Ti and a twice-quenching treatment on the microstructure and ductile brittle transition temperature of 9CrWVTiN steels

Effects of Ti and a twice-quenching treatment on the microstructure and ductile brittle transition temperature of 9CrWVTiN steels

The effects of Ti and a twice-quenching treatment on the microstructure and ductile brittle transition temperature (DBTT) of 9CrWVTiN steels have been studied. The results show that Ti addition reduces austenite grain size and martensitic lath, and moderate Ti (
