粉末燒結成型：使粉末固結成為全致密燒結體

      熱等靜壓工藝可用於生產高密度、細晶粒、高性能和特殊粉末冶金材料和製件。為了獲得均勻而細化的組織，減少材料損耗，減少後續機加工等工序，越來越多的粉末冶金製品采用了熱等靜壓工藝進行成型及致密化。

l  高壓和高溫的同時作用可以降低材料燒結溫度閾值，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  熱等靜壓粉末成型可以提高材料化學成分及分布的均一性，消除偏析，控製晶粒長大，從而提高材料性能；

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  近淨成形工藝可以將粉末直接燒製成接近最終的形狀，極大提高原料利用率，降低成本和機加工難度；

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  可以製備加工大尺寸工件和異形工件；

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