在变形钢条力学性能允许范围内，研究Cr含量的增加对钢中合金材料（如Mn和V）改变的影响，并给出Mn，V等含量的改进范围，设计元素组成的优化方案。

結果 (英文) 1:

Deformation and mechanical properties of steel bars within the allowed range, increased study of Cr content in steel alloys (such as Mn and v) effects of changing, and Mn,V content, such as improved range, optimization of design elements.

結果 (英文) 2:

The mechanical properties of deformed steel bars within the allowable range, consider increasing Cr content in steel alloys (such as Mn and V) the impact of changes, and gives Mn, V and other content to improve the range of design elements optimization.

結果 (英文) 3:

In the allowable range of deformation of steel mechanical properties, the content of Cr increased in steel alloy materials (such as Mn and V) changes, and gives the Mn range of V, improved the content, optimize the design element.
