Hot Rolled

The effects of the microstructure properties on the mechanical properties of C-Si-Mn hot rolled dual phase steel are reported. It was observed that both the amounts of the martensite and the particle size of the ferrite significantly influence the mechanical properties of hot rolled dual phase steel. The aim of our works is to develop a modeling method for controlling the microstructure properties of C-Si-Mn hot rolled dual phase steel through the experimental trend comparison of the aforementioned two factors on their mechanical properties.

Hot Rolled

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.
