使用MSC. Marc软件从颗粒尺度模拟钨颗粒的 HIP 过程。研究了 HIP 压力、HIP 温度、颗粒尺寸比等因素对钨粉在 HIP 过程中的相对密度、局部/整体应力分布、颗粒变形情况、孔隙填充等致密化行为的影响，并分别对上述过程所得的粉体宏观及微观性质进行了表征，并对致密化机理进行了分析。

Use MSC. Marc software to simulate the HIP process of tungsten particles from the particle scale. The effects of HIP pressure, HIP temperature, particle size ratio and other factors on the densification behavior of tungsten powder in the HIP process, such as the relative density, local/overall stress distribution, particle deformation, and pore filling, are studied, and the effects of the above process are respectively affected. The macroscopic and microscopic properties of the powder were characterized, and the densification mechanism was analyzed.
