A method for preventing powder depletion/contamination during a consolidation process provides a can for holding a powdered material; the can having an interior wall; a protective layer is positioned intermediate the powdered material and the interior wall utilizing a sol-gel process utilizing monodisperse nanopowders; and the protective layer being formed from a material selected from the group consisting of nickel alloys, chrome alloys, and combinations thereof.

Method for preventing powder depletion/contamination during consolidation process

A powder metallurgy method includes (a) forming a metallic powder into a shape, (b) thermo-mechanically forming the shape into an article having a polycrystalline microstructure, (c) heat treating the article to cause coarsening of the polycrystalline microstructure, and (d) controlling the grain size homogeneity and distribution in the article formed during coarsening in step (c) by selecting the metallic powder in step (a) to include a metallic powder particle size distribution that is truncated on fine and coarse particle size sides, the selected metallic powder particle size distribution reducing abnormal grain growth such that the polycrystalline microstructure coarsens to a predefined target grain size range.

Powder metallurgy method for making components

A powder filling method includes introducing a tube into a can so that the lower end of the tube is near the bottom of the can. The powder in the can is introduced through the tube. The proximity of the lower end of the tube to the powder is controlled by retracting the tube as the powder fills the can.
