摘要
在标准端淬法的基础上,研制了末端喷油淬火设备来测试42CrMo的淬透性,仍按照标准端淬法对试样端面进行喷油淬火,直至试样冷却。采用热处理数值模拟软件COSMAP,对42CrMo钢的末端喷油淬火过程进行了数值模拟计算,模拟过程中充分考虑了相变的影响及温度-组织-应力/应变三场耦合,得到淬火过程中不同时刻的温度场、组织场、应力场和硬度场。对计算的温度和硬度变化结果进行了试验验证,模拟结果同试验结果基本吻合。
On the basis of end-quenching, end spray oil quenching equipment was researched to test hardenability of 42CrMo, the samples were sprayed oil quenching according standard until those were cool. Numerical simulation of end spray oil quenching process for 42CrMo steel was performed by using COSMAP heat treatment software. The instantaneous variations in temperature, stress, microstructure and hardness of the specimen during the quenching were achieved by com- puter simulation. The temperature and hardness of calculations results was verified by experiments. The test results were basically consistent with the simulated results.
