The manufacture process "BOF-LF-VD-CC" of microalloyed forging steel for automobile was investigated systematically,especially the formation principle of non-metallic inclusions.

High temperature mechanical properties of continuously cast blooms for automobile steel;

The development and application of automobile steels including hot"rolling, cold"rolling and coating products during the Nine-Five Plan were introduced in this paper.

Present Status and Development Trend of Steel for Automobile;

Based on the systematical research for the Nb micro-alloying technology in EAF-CSP process,the effective measures against mixed grains were proposed,and the automobile plate QStE340～460TM was successfully developed by the Nb-Ti micro-alloying technology.

Prediction models of austenite dynamic recrystallization of medium-carbon microalloyed steel during forging process;

In order to lower the flow stress in the cold heading process,the Bauschinger effect of microalloyed steel MFT8 for cold heading bolt was studied.

A martensitic microalloyed steel was prepared by addition of low carbon and suitable alloying elements such as Mn, Si and Cr.
