| Zusammenfassung: | A new HIP process using a visco-plastic pressure medium, named "Q-HIP Process", has been developed. In this process, capsulized powder was charged into the pressure vessel with a lump of visco-plastic pressure medium, and compacted with a stroke of the piston. Compaction in the "Q-HIP Process" was done isostatically as well as that of conventional gas HIP. Three kinds of gas atomized tool steel powders (adamite steel, SKD 11 steel and KHA 30 steel) were completely compacted in a few minutes. Materials consolidated through this process proved to have similar microstructure, bend strength and tensile properties to that of gas HIPed products. 1 ref.--AA |
