Powder handling practices and room temperature consolidation techniques have been of interest with Armstrong process powders due to the sponge-like morphology and low initial tap densities. Cost effective methods to increase the apparent densities of the powders are required to improve volumetric processing considerations and efficiencies in the shipping and handling of powders. However, the pickup of oxygen and other interstitials must be minimized. Powder attrition techniques, such as ball and jet milling, and the resulting chemistries and morphologies will be reviewed. Recent studies investigating the cold consolidation of these powders, including cold hydraulic pressing and roll compaction followed by cold rolling, will also be discussed. Lastly, unique rapid thermal processing technologies will be examined that can be used to modify the initial powder morphology of the Armstrong powder.
Summary: Summary to come.
