What is Powder Metallurgy - Definition Material Properties

Powder metallurgy (PM) is a growing and rappidly evolving branch of metallurgy based on the production of materials in the form of metal powders and the manufacturing of parts from these materials.Powder metallurgy processes can avoid,or greatly reduce,the need to use metal removal processes,thereby drastically reducing yield losses in manufacture and often resulting in lower costs.What is Powder Metallurgy? - Definition from CorrosionpediaNov 15,2013·Powder metallurgy is the process of blending fine powdered materials,pressing them into a desired shape or form (compacting),and then heating the compressed material in a controlled atmosphere to bond the material (sintering).What is Powder Metallurgy? Process,Application Powder Metallurgy Characteristic Powder metallurgy should be heat resistant.The size of the powder particles is to pass the powder through the screen (sieves) having a definite number of meshes.The powder should have good plasticity.
