Abstract: An investigation was carried out of the morphology and microstructure of V-Ti complex carbonitride in steel 09MnVTiN during reheating under analytical electron microscope.The prior V-rich ellipsoid V-Ti complex carbonitride particles are replaced progressively by Ti-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 into 84 and94% at 1400℃ respectively.

Key words: steel 09MnVTiN, microalloyed steel, thermomechanical processing, complex carbonitride
