Questions and Answers
Explain the powder metallurgy process.
The powder metallurgy process consists of mixing elemental or alloy powder, compacting the mixture in a die, and then sintering or heating the resultant shape in a controlled atmosphere.
What are the advantages of powder metallurgy?
Advantages of powder metallurgy include the ability to produce parts with closed dimensional tolerance and good surface finish, minimize scrap losses, fully automate the process, eliminate or minimize machining, and facilitate the manufacture of certain parts by mixing different metals or non-metals.
