The Metal Powder Industries Federation (MPIF)’s Powder Metallurgy Microstructures Database has been updated to include new materials (including 300 and 400 series stainless steel alloys) and to streamline the user experience.

Designed to assist metal powder-based parts manufacturers and end-users in interpreting Powder Metallurgy microstructures, the database intends to build an appreciation for what a powerful tool Powder Metallurgy can be when engineering new components, designing new materials and solving quality problems.

Using the database, users are able to reference materials processed by conventional and elevated-temperature sintering, accelerated cooling rates and other properties to determine the phases and structures of the materials. Specimen preparation and proper selection of etchants are also covered.

This resource was produced in collaboration with Hoeganaes Corporation, North American Höganäs Co., Rio Tinto Metal Powders, and Powder-Tech Associates Inc, all of which volunteered time and resources to prepare photomicrographs and ensure image quality.

The updated database is now live.
