通过轧制热变形的方法，优化一次碳化物形貌及其与基体的协调关系，并对不同热变形工艺下材料的性能进行测试，从而揭示轧制热变形参数—组织改善效果—综合力学性能之间的内在关系，以期对 M50 高端轴承钢工业生产过程中的热加工制度的合理制定提供理论指导。通过合理的热加工工艺使得一次碳化物及基体尺寸、分布得以调整，从而弱化一次碳化物对 M50钢服役寿命的影响，将为高品质、长寿命航发主轴轴承钢的制造提供技术支撑。

Through rolling thermal deformation, the morphology of primary carbides and their coordination with the matrix are optimized, and the material properties under different thermal deformation processes are tested. This study aims to reveal the intrinsic correlation among rolling thermal deformation parameters, microstructure improvement effects and comprehensive mechanical properties, so as to provide theoretical guidance for the rational formulation of hot working regimes during the industrial production of high-end M50 bearing steel. By adjusting the sizes and distribution of primary carbides and the matrix via reasonable hot working processes, the adverse impact of primary carbides on the service life of M50 steel can be mitigated. This work will offer technical support for the fabrication of high-quality, long-life aero-engine spindle bearing steel.
