    摘要: A TiCN-based cermet cutting insert superior in toughness with improved wear resistance includes a binding phase and at least two of four hard dispersion phases. One of the two hard dispersion phases includes at least one of a duplex or triplex phase structure with a core of a composite carbonitride solid solution and a single-phase structure of a composite carbonitride solid solution. The other hard dispersion phase includes one of a hard dispersion phase of titanium carbonitride and a hard dispersion phase which includes a single-phase structure of titanium carbonitride.

    摘要: This invention relates to a catalyst for cleaning exhaust gas, which is prepared by dipping in hydrofluoric acid an amorphous alloy composed of 20 to 80 atom % of one or more elements selected from the group consisting of Nb, Ta, Ti and Zr (the sum of Nb and Ta being up to 70 atom %), 0.5 to 20 atom % of one or more elements selected from the group consisting of Ru, Pd, Rh, Pt and Ir, and the balance of one or two of Ni and Co. This catalyst can clean at a low temperature an exhaust gas containing NO or CO discharged from apparatuses or engines wherein various organic substances are burnt.
