Microstructure and property relationships in hipped Stellite powders

In the present paper the microstructure and properties of a range of hipped Stellite powders are investigated, the basic aim of the study being to gen erate a material/property database to facilitate alloy selection for potent ial applications involving net shape component manufacture. Particular atte ntion is paid to the morphology, particle size distribution, and surface co mposition of the as atomised powders and their effect on subsequent consoli dation. The consolidated powders are fully characterised in terms of micros tructure and the composition and distribution of secondary phases. The effe ct of hipping temperature on the microstructure, hardness, and tensile prop erties of the powders are discussed in terms of the optimum processing temp erature for the various alloys.
