The chief raw materials used in the production of powder metallurgy components are the metal powders. These consist of fine, high purity metal powders produced by processes such as atomisation, ...

Here’s a quick overview of different PM processes that can be found at Metal Powder Industries Federation's site, www.mpif.org (select Intro to PM and then processes). For an in-depth discussion of ...

A high-pressure gas atomization process has garnered an American laboratory at least 16 patents over the last two decades and created a spin-off company. Iver Anderson and Emma White, metallurgists at ...

It is possible to produce components via powder metallurgical processes that have physical properties that approach those of analogous wrought materials. However, to achieve this requires repressing ...

Table I. At a test frequency of 6000 rpm, conventional alloy has an endurance limit of 120 ksi. Powder-metallurgy alloy has an endurance limit of 130 ksi.(click image to enlarge) For the last several ...

Iver Anderson and Emma White, metallurgists at Ames Laboratory, like to show off samples of metal powders encapsulated in custom-made hourglasses to visitors. Dull gray, the powders are barely ...
