Abstract: A flat-shaped fine Fe-Ni alloy powder suitable for use as a magnetic shield coating material for cards or the like. The power has a mean particle size of 0.1 to 30 .mu.m, a mean thickness not greater than 2 .mu.m and a coercive force not greater than 400 A/m. The flat-shaped fine powder is produced by preparing an Fe-Ni alloy powder of a composition which exhibits, in a bulk state, a saturated magnetostriction constant value falling within the range of .+-.15.times.10.sup.-6 and which contains, by weight, 70 to 83% Ni, 2 to 6% Mo, 3 to 6% Cu, 1 to 2% Mn, not more than 0.05% C and the balance Fe and incidental impurities, pulverizing the alloy powder by an attrition mill, and annealing the pulverized powder in a fluidized or moving state in a substantially non-oxidizing atmosphere.

Abstract: The present invention provides a process for the electroless plating of easily reducible metals onto ultrafine, usually inert, particles. Such plating is achieved through careful and accurate control of such parameters as the feed rates of the various solutions, the control of pH of the solution, the temperature, pressure and the rate of agitation of the solution in which the plating is taking place. The plated ultrafine composite particles and the powders made from the particles produced by the process are also a part of the invention. There is also provided a metal article of manufacture consisting of a metal such as copper, silver, gold, ruthenium, rhodium, palladium, osmium and platinum with a plurality of spherical shaped ultrafine particles with a diameter of less than about 10 microns dispersed substantially evenly through the metal article.

Abstract: Materials for cryogenic refrigerator regenerators are formed by a high yield spark erosion cell. The materials are made of erbium or dysprosium and are spherical shaped. The spheres have a diameter range of 150 .mu.m to 400 .mu.m with a packing factor of at least 50%. The materials are made by disposing chunks of a starting material into a liquid dielectric in a spark chamber, agitating the chunks, impressing a spark voltage in order to cause melting of the chunks and formation of spherical particles, and collecting the particles at the bottom of the spark chamber. The particles may then be gathered, dried, and separated.

Abstract: The invention relates to low-nickel copper alloys to be used as brazing filler metals, which alloys also contain phosphor, tin and possibly small amounts of manganese. The alloys are produced by means of rapid solidification. Their advantages are low liquidus temperature and narrow mushy zone. The alloys are mainly used for brazing copper and its alloys.

Abstract: A metal target and a substrate are disposed in confronting relationship in a vacuum chamber whose interior is kept at high vacuum, and laser light is irradiated to the surface of the target to emit a high-speed evaporated material from the target. The high-speed evaporated material is then deposited on the substrate. By applying a predetermined voltage between the target and the substrate, the impact energy of the charged particles in the evaporated material on the substrate are controlled to form an amorphous metal film preferably a pure iron film.

Abstract: A process of aluminizing magnetic steel sheets is disclosed. The process involves annealing a steel sheet in order to achieve partial secondary recrystallization, providing aluminum on the steel sheet, preferably by vacuum evaporation or immersion, and subjecting the steel sheet to a further heat treating step in order to diffuse the aluminum into the sheet and decrease impurities therein. Preferably, the partial secondary recrystallization anneal is performed in a neutral atmosphere such as nitrogen, while the final heat treating step is performed in a hydrogen atmosphere, and at a higher temperature than the above annealing step.

Abstract: The present invention eliminates the problems associated with the use of oxygen-free copper and other high-purity copper materials as bonding wires. In accordance with one aspect of the present invention, at least one rare earth element, or at least one element selected from the group consisting of Mg, Ca, Ti, Zr, Hf, Li, Na, K, Rb and Cs, or the combination of at least one rare earth element and at least one elemented selected from the above-specified group is incorporated in high-purity copper as a refining component in an amount of 0.1-100 ppm on a weight basis, and the high-purity copper is subsequently refined by zone melting. The very fine wire drawn from the so refined high-purity copper has the advantage that it can be employed in high-speed ball bonding of a semiconductor chip with a minimum chance of damaging the bonding pad on the chip by the ball forming at the tip of the wire.In accordance with another aspect of the present invention, 0.
