Effect of Ferrite Grain Size on the Yield-Strength Ratio of Low-Carbon Alloy Steel

Abstract:

Using thermo-mechanical controlled process, the experiment on the yield-strength ratio of low-carbon alloy steel was carried out and the effect of ferrite grain size on the yield-strength ratio of steel was discussed. Theory analysis and the experimental results indicate that the smaller ferrite grain size is, the higher the yield-strength ratio is. In addition, the regression formulas on yield and tensile strength are also obtained.
