    摘要： An internal gear manufacturing method capable of manufacturing time reduction and easy core removal, and a metallic glass internal gear manufactured thereby. A carbon core formed into a shape of an external gear is arranged in a thin, long tubular mold of a length equal thereto with a space extending longitudinally therealong. A molten metal material is pressure-injected under a temperature higher than a melting point thereof into the space between the mold and the core. The molten metal material is resolidified by rapid cooling at or above a critical cooling rate thereof together with the mold and the core. After resolidification of the molten metal material, the core is removed by pulverization or dissolution. Along internal gear formed of the resolidified metal material is cut into a plurality of segments of a prescribed length.

    摘要： An arc melting furnace apparatus is provided which reduces an operation burden on a worker and shortens working hours. An arc melting furnace apparatus 1 includes a housing 2 having formed therein a melting chamber 2a, a hearth 4 provided within the melting chamber 2a and having a recessed portion 4a, and a heating mechanism 10 for heating and melting a metal material supplied into the recessed portion 4 to generate an alloy ingot. The apparatus comprises a turning member 23 rotatably supported on a supporting member 21 standing within the melting chamber 2a, a perimeter edge of the turning member 23 rotating and moving along the inner surface of the recessed portion 4a to lift the alloy ingot generated in the recessed portion 4a above the hearth 4 and turn it over, and a resilient turn-over assisting member 24 provided above an upper end of the recessed portion 4a. Further, the turn-over assisting member 24 is arranged to flex by a predetermined amount when the alloy ingot abuts it, and to return to its original state from the flexed state so that the alloy ingot is urged to drop into the recessed portion 4a.

    摘要： An aluminum base alloy is produced by supercooling a molten alloy composed mainly of aluminum. The molten alloy contains an element capable of forming a quasicrystalline phase, an element which aids formation of the quasicrystals, and an element which stabilizes a supercooled state of the molten alloy and delays crystallization of a crystalline phase, and is composed of a mixed composition of a fine amorphous phase and an aluminum crystalline phase or an aluminum supersaturated solid solution phase, or a single phase of only an amorphous phase.
