High Nickel Alloys Offering a Combination of High Strength and High Impact Properties

ABSTRACT High nickel steels offer the opportunity to produce powder metallurgy components with excellent high strength and ductility combinations. These alloys are a sinter-hardenable class of materials that do not require conventional heat treatment processes to develop these unique properties. The alloys must be sintered at high temperatures in order to obtain the value of […] Read More
Wear Resistance and Mechanical Properties of Selected PM Aluminum Alloys and Composites

ABSTRACT Wear resistance is often important in structural applications that use light weight PM aluminum alloys. Several aluminum PM alloys were evaluated for wear resistance using the ASTM G65 test method. This consists of dry sand that is dropped into the interface between the test sample and a rotating rubber wheel. Test results indicate that […] Read More

Machining of P/M Steels

Howard Ferguson, MPP Director of Technology The rapid growth of P/M is primarily due to its net-shape part-making capability. In the past, the primary P/M process (compaction, sintering, and – where applicable – sizing) was sufficient for most P/M applications. However, dimensional precision has tended to steadily increase. A recent survey by the P/M industry […] Read More
