利用热力学计算软件Thermo-Calc和Gleeble物理模拟技术辅助进行抗剥离车轮钢的合金设计。热力学计算结果显示,从成分设计的角度出发,提高Si含量和降低C含量会提高车轮钢的相变点,可有效抑制车轮钢的制动剥离现象。动态升温模拟试验也说明,提高Si含量可改善车轮钢的抗剥离性能。但是,降低C含量也带来车轮钢耐磨性的降低,而提高Si含量则在基本不损害塑性的情况下,显著提高车轮钢的强度。
Thermomechanical calculation software Thermo-Calc and Gleeble physical simulation techniques are used to assist in alloy design of anti-stripped wheel steel. Thermodynamic calculation results show that, from the point of view of composition design, increasing the Si content and decreasing the C content will increase the transformation point of the wheel steel, which can effectively restrain the wheel steel stripping phenomenon. Dynamic temperature simulation test also shows that increasing the Si content can improve the anti-peel performance of steel wheels. However, reducing the C content also leads to a decrease in the wear resistance of the wheel steel, while increasing the Si content significantly increases the strength of the wheel steel without substantially impairing the plasticity.
