Abstract: The sliding member of the present invention comprises a particle aggregate of base material particles and hard particles at least on a surface.
The hard particles are iron-based alloy particles containing 35 to 90% by area (inclusive) of molybdenum silicide, and it is therefore possible to provide a sliding member having wear resistance equivalent to that of a sliding member that uses cobalt-based hard particles.

Abstract: A spinodal copper-nickel-tin alloy with a combination of improved impact strength, yield strength, and ductility is disclosed. The alloy is formed by process treatment steps including solution annealing, cold working and spinodal hardening. These include such processes as a first heat treatment/homogenization step followed by hot working, solution annealing, cold working, and a second heat treatment/spinodally hardening step. The spinodal alloys so produced are useful for applications demanding enhanced strength and ductility such as for pipes and tubes used in the oil and gas industry.

Abstract: A sliding member 10 includes a substrate 11 containing Fe as a main component and an alloy layer 12 overlaid on the substrate 11 and composed of a Cu-base alloy containing 6 to 12% by mass of Ni and 3 to 9% by mass of Sn. The alloy layer 12 has a body layer 15 and an intermediate layer 16. The body layer 15 is formed of the Cu-base alloy, while the intermediate layer 16 is composed of an alloy containing Ni, Sn, and Cu which are derived from the Cu-base alloy and Fe derived from the substrate 11. In an arbitrary observation section taken along the thickness direction thereof, when the alloy layer 12 is divided at the middle in the thickness direction to set a side close to the substrate 11 as a lower region and the other side as an upper region, a ratio of the total area of hard phases 17 to the observation section of the upper region is 1.2 to 3.0, where the ratio of the total area of the hard phases 17 to the observation section of the lower region is set at 1.

Abstract: Provided is a technique for obtaining metal powder having little variation in particle size by stabilizing the supply amount of molten metal when manufacturing the metal powder by means of atomization. The present invention is an atomization device 1 for manufacturing metal powder by spraying a fluid to molten metal M, said device comprising: a tundish 11 into which the molten metal M is poured and discharged from a discharge nozzle 11N installed on a bottom part 11b; fluid spray nozzles 12 disposed below the tundish 11 and spraying the fluid to the molten metal M dropping from the tundish 11; a means for measuring a molten-metal surface height Mh inside the tundish 11 from an image obtained by imaging the inside of the tundish 11; and a means for, upon calculating an amount of the molten metal M to be poured into the tundish 11 from the molten-metal surface height Mh, discharging the molten metal in such a manner that the height is maintained substantially constant. The interior of the tundish 11 is formed in such a shape that the area of the molten-metal surface of the poured molten metal M increases with height in the vertical direction.
