| Abstract: | Some type of ultra fine Ti oxides could refine the grains by acting as heterogeneous nucleation sites of intragranular ferrite(IGF).The type of precipitated Ti oxide was affected by oxygen content,alloying elements contents of liquid steel.A thermodynamic study of the type of precipitated oxide in X80 pipeline steel was presented.The results showed that the Al/Ti ratio should be controlled to ensure the Ti oxides precipitating during steel solidification.Ti3O5 was the most stable among all Ti oxides in the ... |
