摘要：

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. © 2023 Chinese Mechanical Engineering Society.
