    Abstract: One aspect of this titanium carbonitride-based cermet insert has a microstructure including 75 to 90 area % of a hard phase and the balance as a binding phase, wherein the hard phase includes a first hard phase in which a core-having structure includes a TiCN phase and a peripheral portion includes a (Ti,W,Ta/Nb)CN phase, a second hard phase including a (Ti,W,Ta/Nb)CN phase, and a third hard phase including a TiCN phase, and the binding phase contains 18 to 33% of Co, 20 to 35% of Ni, 5% or less of Ti and Ta and/or Nb, and 40 to 60 mass % of W. In another aspect of this cermet insert, a total of an amount of Ti converted as carbonitride, an amount of Ta and/or Nb converted as carbide, and an amount of W converted as carbide is 70 to 95 mass %, an amount of W converted as carbide is 20 to 35 mass %, and Co and Ni are 5 to 30 mass %, this cermet insert has a microstructure including a hard phase containing (Ti,W,Ta/Nb)CN and a binding phase containing, as main components thereof, W and Co and/or Ni, and 40 to 65 mass % of the W is contained in the hard phase. This cutting tool includes a holder and the cermet insert described above held and fixed by the holder.

    Abstract: An object of the present invention is to provide a porous liquid absorbing-and-holding member having a high absorbing capacity for a liquid owing to capillarity and having in itself a structure capable of holding a large amount of the liquid, a process for producing this member, and a member for absorbing and holding an alcohol used as a fuel for a fuel cell. The porous liquid absorbing-and-holding member provided by the present invention is that including a porous sintered product having a skeleton formed by sintering of metal powder around voids and subjected to hydrophilicity-imparting treatment. The hydrophilicity-imparting treatment is preferably the formation of one or more substances selected from the group consisting of silicon oxides, titanium oxides, chromium oxides and aluminum oxide on the skeleton.

    Abstract: A method of manufacturing a metal-graphite brush material for a motor, which allows high-density formation of copper particles on the surfaces of graphite particles. The method: attaches copper complex to graphite particles; heat-treats the graphite particles attached with the copper particles, thereby to pyrolyze the copper complex to form copper particles on the surfaces of the graphite particles; forms the graphite particles having the copper particles formed thereon, together with a resin, into a formed product; and reduction-sinters the formed product under a reducing atmosphere to pyrolyze the resin, thereby to form a sintered body and also to reduce copper oxide formed in surface layers of the copper particles during the heat-treating.
