摘要/Abstract

摘要： 为探究合金元素变化对渗碳淬火齿轮性能的影响规律,以20MnCr5低碳合金钢制齿轮为研究对象,利用JMatPro软件计算得到两种含不同合金元素的20MnCr5钢的材料性能参数;基于有限元方法开展齿轮渗碳淬火模拟分析,根据实际热处理工艺路线,建立渗碳淬火过程的数学模型,通过COSMAP软件模拟了齿轮的渗碳淬火热处理工艺过程,对比分析合金元素变化对渗碳淬火20MnCr5钢齿轮的温度场、组织场和硬度场的作用结果。研究表明,模拟值与试验值具有较好的一致性。温度场和渗碳层对合金元素含量的变化反应不明显,而渗碳淬火后的组织分布和硬度分布受C、Mn、Cr、Al等合金元素变化的影响较大。

Abstract: In order to investigate the influence of alloying element change on properties of gears during carburizing and quenching, mild steel 20MnCr5 gears were used as the research object, and the performance parameters of two kinds of 20MnCr5 steel with different alloying elements were calculated by using JMatPro software. The carburizing and quenching processes of gears were simulated and analyzed based on the finite element method, and a mathematical model for the carburizing and quenching process was established according to the actual heat treatment process route. By using COSMAP software to numerical simulate the heat treatment process, and the effect of alloying element on temperature, microstructure, and hardness of the carburized 20MnCr5 steel gears was compared The results show that the simulated values are verified to be in good agreement with the experimental values. The temperature field and carburized layer have no obvious response to the change of material element content, while the microstructure distribution and hardness distribution after carburizing and quenching are more influenced by the change of alloying elements such as C, Mn, Cr and Al.

Key words: 20MnCr5 steel, alloying element, gear, carburizing and quenching, COSMAP simulation
