Compaction is generally performed at room temperature, and the elevated-temperature process of sintering is usually conducted at atmospheric pressure and under … See more 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 … See more Any fusible material can be atomized. Several techniques have been developed which permit large production rates of powdered particles, often with considerable control over the size ranges of the final grain population. Powders may be prepared by … 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 to the direct pressure applied by the die faces of a die pressing process. The … See more The history of powder metallurgy and the art of metal and ceramic sintering are intimately related to each other. Sintering involves the … 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 … See more After compaction, powdered materials are heated in a controlled atmosphere in a process known as sintering. During this process, the … See more The phrase "continuous process" should be used only to describe modes of manufacturing which could be extended indefinitely in time.
