Made by mixing elemental or alloy powders and compacting the mixture in a die, the resultant shapes are then sintered or heated in a controlledatmospherefurnace.
通过混合元素或合金粉末并在模具中压实混合物，再烧结或在环境可控炉内加热制成最终形状。

Quenching and tempering heat treatment process for raw materials, temperature control, controlledatmospherefurnace, quenching medium, such as strict requirements.
调质热处理工艺对原材料、炉温控制、炉内气氛控制、淬火介质等都有严格的要求。
