Influence of forging cooling process on microstructure and properties of HN2154 microalloyed steel

Wang Xin-she

Abstract

Effect of different cooling processes after forging on microstructure and mechanical properties of HN2154 microalloyed steel was studied,and a CCT curve of HN2154 steel was measured.The results show that the strength of HN2154 steel forgings increases firstly and then decreases after a maximum with increasing of cooling speed,which is mainly concerned with precipitation of VN or V(C,N) particle.According to this study,there is a best cooling process after forging in order to obtain the best mechanical properties of HN2154 steel forgings.
