BEHAVIOR OF FINE V-Ti COMPLEX CARBONITRIDE IN STEEL 09MnVTiN DURING REHEATING

摘要

An investigation was carried out of the morphology and microstructure of V-Ti complexcarbonitride in steel 09MnVTiN during reheating under analytical electron microscope.Theprior V-rich ellipsoid V-Ti complex carbonitride particles are replaced progressively byTi-rich cubic ones as the reheating temperature elevated from 1050 to 1400℃.The Ti con-tents in the core and border of particles increase from 15 and 6% in hot-rolled specimens into84 and94% at 1400℃ respectively.
