Powder Metallurgy Fundamental Manufacturing Processes Study Guide DV03PUB20 - 4 - Review Questions 1 Parts produced by powder metallurgy: a require final machining b cannot be heat treated c require subsequent forging d are of net or near net shape 2 The most common powders used are: a aluminum and magnesium
Powder metallurgy (PM) is a metal processing technology in which parts are produced from metallic powders In the usual PM production sequence the powders are compressed into the desired shape and then heated to cause bonding of the particles into a hard rigid mass
Powder metallurgy process consists from four major steps: Production of the metallic powder Mixing and preparation of powder Pressing of powder to the required shape Heating or sintering of the compacted powder at a relatively high temperature In addition to Post Processing as shown in figure 1 & 2
