Effect of Coiling Temperature on Microstructure of High Strength V-microalloyed Automobile Steel Plates
The effects of coiling temperature on the microstructure and the precipitation of V(C,N)in high strength V-microalloyed automobile steel plates were investigated through four-pass compression with different colling temperature using Gleeble 1500 hot simulation machine and the metallographic analysis and TMP observation.The results show that the best coiling temperature and the best precipitation temperature is 650℃under setting processes.
