## Description

- description: "(Ta,W)C bulks were prepared by spark plasma sintering. Densification
    kinetics and solid-solution formation kinetics were performed on the powder mixtures
    using TaC and W powders. The as-received tungsten powder had a spherical shape
    and rather coarse size. By using the crushed and as-received powder, it can be
    suggested that sintering at 2000°C limits the reaction volume to 3–6 μm and hence
    allows forming a complete solid-solution using finer powders. The lattice parameter,
    hardness, toughness, and strength were investigated as a function of the TaC content.
    The flexural strength of the (Ta,W)C ceramic bulks was investigated up to 2000°C
    and it was found that the maximum strength was for the 60 mol.% TaC composition.
    Strength as a function of the temperature tended to increase up to 1200°C followed
    by a gradual decrease to 2000°C. When the TaC was reinformed by coarse W spheres,
    the flexural strength monotonically decreased from 570 MPa at room temperature
    to 220 MPa at 2000°C."
