标准摘要
[中文适用范围]： 粉末金属 (P/M) 零件是通过在精密模具中将金属粉末压制成所需形状并烧结以在颗粒之间产生冶金结合从而产生适当的机械性能来制造的。随后可以通过压制或通过诸如此类的常规方法来修改零件的形状和机械性能。如机械加工和/或热处理。虽然粉末冶金涵盖了金属粉末可用作原材料的许多领域，但该标准主要涉及与铁基材料生产的机械部件和轴承相关的信息。 [外文原描述]： Powder metal (P/M) parts are manufactured by pressing metal powders to the required shape in a precision die and sintering to produce metallurgical bonds between the particles, thus generating the appropriate mechanical properties. The shape and mechanical properties of the part may be subsequently modified by repressing or by conventional methods such. as machining and/or heat treating.While powder metallurgy embraces a number of fields wherein metal powders may be used as raw materials, this standard is concerned primarily with information relating to mechanical components and bearings produced from iron-base materials.Cross Reference:
