Powder metallurgyWikipedia
Overview. The powder metallurgy press and sinter process generally consists of three basic steps powder blending (pulverisation) die compaction and sintering. Compaction is generally performed at room temperature and the elevated-temperature process of sintering is usually conducted at atmospheric pressure and under carefully controlled atmosphere composition.
