Paper Title:
Effects of Finish-Rolling Reduction on Microstructure and Mechanical Properties for C-Si-Mn Hot Rolled Dual-Phase Steel
  Abstract

The experiments were carried out on the φ450 hot rolling mill at the State Key laboratory of Rolling and Automatic of Northeastern University. The effect of different finish-rolling reduction on the microstructure and mechanical properties of C-Si-Mn hot rolled dual-phase steel were studied. It is found that the grain size of the ferrite would be finer with the increasing of finish-rolling reduction. Through the controlling of the finish-rolling reduction, grain size of the ferrite can be finer, so the better properties can be obtained by fine grain and sub-grain strengthened. With the low volume of lath martensite, the elongation of sample is high, the yield-strength ratio is low, and complex properties are better.
