粉末烧结成型：使粉末固结成为全致密烧结体

      热等静压工艺可用于生产高密度、细晶粒、高性能和特殊粉末冶金材料和制件。为了获得均匀而细化的组织，减少材料损耗，减少后续机加工等工序，越来越多的粉末冶金制品采用了热等静压工艺进行成型及致密化。

l  高压和高温的同时作用可以降低材料烧结温度阈值，降低粉末成型能耗；

l  Simultaneous application of high pressure and high temperature can lower the sintering temperature threshold and reduce the energy consumption of the powder molding;

l  热等静压粉末成型可以提高材料化学成分及分布的均一性，消除偏析，控制晶粒长大，从而提高材料性能；

l  HIP powder compacting can improve the uniformity  of chemical composition and distribution, eliminate segregation and control the crystal grain growth, thus to improve the material properties;

l  近净成形工艺可以将粉末直接烧制成接近最终的形状，极大提高原料利用率，降低成本和机加工难度；

l  High purity and fine grain powders are formed (consolidated) into semi-finished product with minimal deterioration due to impurities, oxidation or grain growth (i.e. Sputtering Targets). Using the HIP/PM route materials and structures may be produced that are not available by more conventional (casting) techniques.

l  可以制备加工大尺寸工件和异形工件；

l  Able to prepare and process large size workpiece and special-shaped workpiece;
