The distribution,morphology and size of precipitation in V-Mo-N microalloyed steel with various V content had been studied via thermal simulation and TEM observation. Hardness test was also carried out.The result shows that the second phase seems to be V(C,N) without Mo which is almost solute in the matrix. As the vanadium addition increases,the structure morphology transfers from lath bainite into granular bainite,at the same time the amount of vanadium precipitate and hardness of the steels increase.
