粉末材料的热等静压过程在一系列成形工艺中占有特殊地位，这是因为粉末材料的压缩与变形是靠均匀的外界压力实现的，而不是靠通常的要移动工作器具来实现． 如果在大多数典型的金属压力加工过程中决定变形抗力大小的仅仅是受力条件，那么在热等静压时决定它的既有最终热力参数 The hot isostatic pressing of powder material occupies a special place in a series of forming processes because the compressive deformation of the powder material is achieved by a uniform external pressure rather than the usual movement of the work tool. If, in most typical metal pressure processes, the magnitude of the deformation resistance is only the stress condition, then the final hydrothermal parameter
