Effect of Rolling Deformation on Yield Ratio in a Low-Alloy Steel

摘要：

　　The microstructures have been investigated in steel plates with different rolling processes to find the reasons of yield ratio overseted standard in low-alloy steel plates.The effects of rolling path,rolling path depress ratio on microstructure and properties have studied.Some reasons of yield ratio overseted standard have been analyzed.The results show that decreasing rolling paths and increasing depress ratio refined grains but unchanged volume ratio and interlamellar spacing of pearlite.Yield strength excessively increased but tensile strength unchanged increased yield ratio.

关键词： yield ratio rolling deformation grain refining interlamellar spacing low alloyed steel
