    Abstract: Described herein is a method for sintering a composite material including at least one metal phase and at least one ceramic phase. The method comprises the following steps:
    - providing the at least one metal phase in the form of powders of pre-alloyed metal material;
    - providing the at least one ceramic phase in the form of powders of ceramic material;
    - mixing the powders of the at least one metal phase and of the at least one ceramic phase; and
    - sintering the mixed powders for a time interval of between 10 -4 s and 60 s,
    wherein one or more metal phases have a coefficient of thermal expansion of between 0 K -1 and 6·10 -6 K -1 .

    Abstract: There are provided a permanent magnet and a manufacturing method thereof enabling carbon content contained in magnet particles to be reduced in advance before sintering even when wet milling is employed. Coarsely-milled magnet powder is further milled by a bead mill in a solvent together with an organometallic compound expressed with a structural formula of M-(OR) x (M includes at least one of neodymium, praseodymium, dysprosium and terbium, each being a rare earth element, R represents a substituent group consisting of a straight-chain or branched-chain hydrocarbon, x represents an arbitrary integer) so as to uniformly adhere the organometallic compound to particle surfaces of the magnet powder. Thereafter, a compact body of compacted magnet powder is held for several hours in hydrogen atmosphere at 200 through 900 degrees Celsius to perform hydrogen calcination process. Thereafter, through sintering process, a permanent magnet 1 is manufactured.

    Abstract: A cermet tool is provided that reduces machined surface roughness of a work piece material, is excellent in wear resistance, fracture resistance, and chipping resistance, and is capable of extending tool life. The cermet tool includes from 75 to 95 volume% of a hard phase and from 5 to 25 volume% of a binder phase, wherein the hard phase has a first hard phase with a core portion of (Ti, Nb, Mo) (C, N) and a peripheral portion of (Ti, Nb, Mo, W) (C, N) or (Ti, Nb, Mo, W, Zr) (C, N), a second hard phase with both a core portion and a peripheral portion of (Ti, Nb, Mo, W) (C, N) or (Ti, Nb, Mo, W, Zr) (C, N), and a third hard phase of (Ti, Nb, Mo) (C, N), Nbs/Nbi that is a relationship between a maximum Nb amount Nbs in a surface region and an internal Nb amount Nbi in an internal region is from 0.8 to 1.2, Ws/Wi that is a relationship between a maximum W amount Ws in the surface region and an internal W amount Wi in the internal region is from 1.0 to 1.5, and area ratios A1, A2, and A3 of the respective hard phases are from 75 to 95 area% for A 1, from 4 to 24 area% for A2, and from 1 to 24 area% for A3.
