TLDR
In this paper, modern atomizing techniques and parameters are reviewed in terms of their economics and influence on powder properties, chemistry, ultimate structural control, property reliability, and alloy and process flexibility, especially with materials difficult to fabricate.Abstract:
Reduced iron, copper-base, and refractory metal powders have dominated the raw-material field during the rapid growth of the PM industry in the last 30 years. Emphasis has been on the economic mass production of structural parts, rather than on properties. New material concepts have brought about the need for new and improved powders possessing enhanced properties and performance reliability, i.e. atomized powders. Modern atomizing techniques and parameters are reviewed in terms of their economics and influence on powder properties, chemistry, ultimate structural control, property reliability, and alloy and process flexibility, especially with materials difficult to fabricate.read more
