Powder Metallurgy (PM) is a process for fabricating components by compacting finely powdered metallic or non metallic or both materials. It is solid state fabrication technique. Two or more metallic and/or non metallic powders are thoroughly blended together in a machine and then compacted at very high pressure using a die.
