摘要/Abstract

摘要： 马氏体时效钢磨削精加工后，通过组织均匀化可获得“高比强、高韧性”的表面性能，现已作为航空航天等领域关键结构件的优选材料。但在磨削高应变率和温升率作用下，由于微观组织与力热载荷在不同尺度上的相互制约，导致机械应力、热应力生成过程很难量化解析，从而给通过优化磨削工艺以控制残余应力分布带来了严峻的挑战。以微观组织中位错与织构演变为切入点，通过对马氏体时效钢3J33进行磨削试验，分析了工艺参数对位错与织构的影响规律，量化位错与织构对流动应力的影响，构建考虑位错与泰勒因子的流动应力模型和考虑位错与织构的磨削力模型与叠加热源温度场模型，并且在该磨削力磨削温度模型基础上，提出了基于机械和热应力加载与卸载的残余应力解析方法，并分析了残余应力的工艺敏感性以及微观组织的影响规律。结果表明，考虑微观组织影响的残余应力模型预测精度在X方向提升了16.45%，在Y方向提升了16.01%，且提高进给速度、砂轮线速度以及磨削深度有利于增大位错密度和减小泰勒因子，并且能够提高表面残余压应力。

Abstract: Maraging steel with the homogenization of the structure can be obtained through the grinding surface properties of "high specific strength and high toughness", and it has been used as the preferred material for key structural parts in aerospace and other fields. However, under the action of high strain rate and temperature rise rate in grinding, due to the mutual restriction of microstructure and mechanical and thermal loads on different scales, it is difficult to quantify and analyse the generation process of mechanical stress and thermal stress, so as to optimize the grinding process to control residual stress distribution presents serious challenges. The dislocation and texture in the microstructure are taken as the starting point. through the grinding test of maraging steel 3J33. the influence of process parameters on the dislocation and texture is analysed, and the flow stress of the dislocation and texture is quantified. The flow stress model considering dislocation and Taylor factor, the grinding force model and the superimposed heat source temperature field model considering dislocation and texture are constructed, and on the basis of the grinding force grinding temperature model, an analytical method for residual stress based on mechanical and thermal stress loading and unloading is proposed. and residual stress after thermal loading relaxation. On this basis, the process sensitivity of residual stress and the influence law of microstructure are analysed. The results show that the prediction accuracy of the residual stress model considering the influence of microstructure is improved by 16.45% in the X direction and 16.01% in the Y direction, and increasing the feed rate, the grinding wheel linear speed and the grinding depth is beneficial to increase the dislocation density and the Taylor factor is reduced, and the surface residual compressive stress can be increased.
