EFFECT OF Mo ADDITION ON THE PRECIPITATION BEHAVIOR OF CARBIDE IN Nb-BEARING HSLA STEEL

摘要：

　　The effect of Mo addition on the precipitation of carbides both in austenite and ferrite of Nbbearing HSLA steel were investigated by stress relaxation and transmission electron microscopy(TEM).Experimental results showed that the addition of~0.2 wt.%Mo into Nb-bearing steel slightly accelerated the precipitation kinetics of Nb carbides both in austenite and ferrite.The particles,(Nb,Mo)C,precipitated in Nb-Mo-bearing steel exhibit superior coarsening resistance compared to that of NbC particles in Nb-bearing steel.And the difference of carbides precipitated in anstenite and ferrite of Nb-Mo-bearing steel was discussed.
