  • Fabrication method of nanostructured tungsten carbide bulk material
    Patent number: 6814927
    Abstract: A nanostructured tungsten carbide bulk material, sintered from tungsten carbide and metal such as cobalt nano-powders, comprises a tungsten carbide and a metallic binder such as cobalt phases. The tungsten carbide phase has nanostructures comprising a plurality of dislocations, twins, stacking faults, dislocation cells, nano-subgrains with preferred orientation or texture, or a combination thereof.
    Type: Grant
    Filed: November 15, 2002
    Date of Patent: November 9, 2004
    Assignee: Industrial Technology Research Institute
    Inventors: Shih-Chieh Liao, Song-Wein Hong, Geoffrey Wen Tai Shuy, Jin-Ming Chen, Thiraphat Vilaithong, Lang Deng Yu
