POWDER METALLURGY

Why Powder Metallurgy is Important •PM parts can be mass produced to net shape or near net shape, eliminating or reducing the need for subsequent machining •PM process wastes very little material - about 97% of the starting powders are converted to product •PM parts can be made with a specified level of porosity, to produce porous metal parts Get price

Metallurgy

Powder metallurgy. Powder metallurgy (P/M) consists of making solid parts out of metal powders. The powder is mixed with a lubricant, pressed into a die to form the desired shape, and then sintered, or heated to a temperature below the melting point of the alloy where solid-state bonding of the particles takes place. In the absence of any external force, sintering typically leaves the sample Get price
