  • Patent number: 5651808
    Abstract: A new carbothermic reaction process is described for the thermochemical processing of nanophase WC-Co powders. The process permits shorter reaction times, reduced temperatures, and finer microstructures compared to conventional processing methods.The process builds on our experience with spray conversion processing [1], but involves 1) chemical vapor infiltration reaction of the carbon infiltrant and particle substrate to from WC-CO; and 2) removal of any excess (unreacted) carbon by controlled gasification. A feature of the carbothermic reaction process is its adaptability to conventional WC-Co processing technology, as well as to spray conversion processing technology.The resulting power particles consist of a network of fine grains, (less than 100 nm) of WC and Co with interconnected fine porosity. Powder particles suitable for subsequent handling and consolidation are readily produced with diameters greater than 10 microns.

    Abstract: A process for the manufacture of dispersion-strengthened alloys of the refractory metals of the 4th, 5th and 6th subgroups of the Periodic Table for application in semi-finished products or preformed parts requiring high thermal creep-resistances, involves integrating dispersion-strengthening into the process in 2-4 partial operational steps through thermal reshaping, utilizing only 3-25% strain per partial step. Annealing processes are implemented between the individual reshaping processes at temperatures, which at least during some part of the annealing process, are below the respective recrystallization temperatures of the alloy materials. The maximum deformation of the alloy materials is 75%, but is normally substantially lower. Components manufactured from the materials produced according to the process include tools used in isothermic high-temperature forging or in rotating anode X-ray tubes.
