Abstract：
|
|
The effect of the different rolling temperature,reduction and lubrication conditions on the microstructure and the way of precipitation of Ti-IF steel rolled in the ferrite zone were studied using optical microscope,scanning electron microscope and electron probe.The results show that with the rolling temperature increasing and reduction decreasing,the nucleation rate increases which refines the grain size,and the orientation of {111} in the crystal structure is strengthened. The lubrication conditions mostly influece the surface grain size of the samples,and the better the lubrication conditions are,the closer the surface grain size is to the center grain size. The precipitation mainly appears independently,and the formation mechanism of Ti(C,N)-Al2O3 is epitaxial growth.
