航空金属材料热加工仿真研究现状

Research status of hot working simulation of aeronautical metal materials

目前,双碳目标日益成为我国经济高质量发展的绿色引擎,而热加工作为改善金属材料使用性能的重要基础工艺,存在着影响因素众多、研发周期长的问题。因此,开展模拟工艺参数优化设定、多场耦合实体仿真以及精细化控制工艺,进行材料组织-变形-性能协同调控方法的研究是十分必要的。介绍了近年来国内外热加工数值模拟方法,并对典型航空金属材料热加工数值模拟研究进展进行了介绍,最后对未来发展方向进行了展望。

At present,the dual-carbon target has increasingly become a green engine for the high-quality development of Chinese economy,and hot working,as an important basic process to improve the performance of metal materials,has many influential factors and a long research and development cycle.Therefore,it is necessary to carry out the optimization setting of simulation process parameters,multi-field coupling entity simulation,and fine control process,and to study the cooperative control method of material organization,deformation,and property.In this paper,the numerical simulation methods of hot working at home and abroad in recent years are introduced,and the research progress of numerical simulation of typical aeronautical metal materials is introduced.Finally,the future development direction is projected.
