Abstract:
Isostatic pressing has several benefits over the commonly used press and sinter method, including equal compaction in all directions and a more uniform final component density. Nevertheless, as with other powder metallurgy processes, manufacturers must carefully characterize the metal powder’s properties for the process to be successful. Commonly characterized physical properties include powder flow, density, hardness, particle size, and particle shape of the respective powders.Other key characteristics include chemistry and microstructure. Chemistry is paramount as the powder needs to comply with the alloy composition of the material specified, while phase composition and grain size can affect powder hardness and melt behavior which can affect the forming and sintering process.In this study we are focusing on the complementary use of X-ray powder diffraction (XRPD), X-ray fluorescence (XRF), and Automated Imaging to evaluate the performance of various iron-based alloys for use in a Cold Isostatic Pressing (CIP) manufacturing process.
