Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders. PM processes can reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product. Powder metallurgy is also … See more 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 … See more Any fusible material can be atomized. Several techniques have been developed which permit large production rates of powdered particles, … See more Isostatic powder compacting is a mass-conserving shaping process. Fine metal particles are placed into a flexible mould and then high fluid pressure is applied to the mold, in contrast … See more After compaction, powdered materials are heated in a controlled atmosphere in a process known as sintering. During this process, the surfaces of the particles are bonded and desirable properties are achieved. Sintering See more The history of powder metallurgy and the art of metal and ceramic sintering are intimately related to each other. Sintering involves the production of a hard solid metal or ceramic piece from a starting powder. The ancient Incas made jewelry and other artifacts … See more Powder compaction is the process of compacting metal powder in a die through the application of high pressures. Typically the tools are held in the vertical orientation with the punch tool forming the bottom of the cavity. The powder is then compacted into a shape and … See more The phrase "continuous process" should be used only to describe modes of manufacturing which could be extended indefinitely in time. Normally, however, the term refers to … See more

WebWhat is powder metallurgy? Powder metallurgy is a metal-forming process performed by heating compacted metal powders to just below their melting points. It encompasses conventional press-and-sinter technology, metal injection molding, isostatic pressing, metal additive manufacturing (metal 3D printing), and powder forging.
