The excellent mechanical properties of maraging steel 3J33C make it desirable for a wide spectrum of high-strength applications, which would also mean that it is difficult to machine. The application of surface-active media onto the pre-machined surface is explored to improve the machinability of this high-strength material. This mechanochemical effect, named after its discoverer as the Rehbinder effect, was implemented using a marker ink to reduce machining forces and deformed chip thicknesses, and significantly improve the machined surface quality. Machined subsurface microstructure characterization reveals the occurrence of grain refinement with evenly distributed orientations and the microstructure texture components when cutting with the mechanochemical influence. This work also demonstrates with an analytical model the effectiveness of the Rehbinder effect when coupled with the tool-edge radius effect. Lastly, numerical simulations are developed for chip evolution and cutting forces in machining a polycrystalline workpiece material with the mechanochemical influence by modifying the fracture energy.

马氏体时效钢3J33C的优异机械性能使其成为各种高强度应用的理想之选，这也意味着很难加工。探索了将表面活性介质施加到预加工表面上的方法，以提高这种高强度材料的可加工性。这种机械化学作用，以其发现者命名为Rehbinder效应，是通过使用标记墨水来实现的，以减小加工力和变形的切屑厚度，并显着提高加工的表面质量。机加工的亚表面微观结构表征揭示了在受到机械化学影响的切削过程中，晶粒细化具有均匀分布的取向的发生，并且微观结构纹理成分的出现。这项工作还通过分析模型证明了Rehbinder效应与刀沿半径效应相结合的有效性。最后，通过改变断裂能，在机械化学影响下加工多晶工件材料时，针对切屑发展和切削力进行了数值模拟。
