Containerless Consolidation of Mg Powders Using ECAE

In this article, we present results of consolidation of Mg powders using equal channel angular extrusion. A novel feature of the processing is that we were able to compact the powders without either prior cold compaction or canning of the powders. Increased hydrostatic pressure was used to aid the consolidation using the simple expedient of a metal plug in front of the powder. The porosity, density, and tensile properties of the resulting compacts are described.
