摘要： A high strength aluminum alloy is expressed by a general formula, Al.sub.a X.sub.b Mm.sub.c, in which "X" stands for at least one element selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zr, "Mm" stands for a misch metal, a content "a" of aluminum falls in a range of from 95.2 to 97.5 atomic %, and a content "b" of "X" and a content "c" of the "Mm" fall in a hatched area enclosed by points "A," "B," "C" and "D" of accompanying FIG. 1 on atomic % basis, and whose metallic phase includes microcrystalline phases or mixed phases containing amorphous phases in a volume content of less than 50% and the balance of microcrystalline phases. As a result, the amorphous phases or the microcrystalline phases are dispersed uniformly in its base microcrystalline phases appropriately, and at the same time the thus generating base microcrystalline phases are reinforced by forming solid solutions including the "Mm" and the transition metal element "X" as well. Hence, the high strength aluminum alloy comes to have a low specific gravity and a high strength which have not been available from conventional Al amorphous alloys.

摘要： The present invention provides an additive powder for coating materials or plastics, comprising a particle of a metal or glass, comprised of a particle having a thickness of 0.5 to 5 .mu.m, a minor axis/major axis of from 5 to 500 .mu.m, an aspect ratio (ratio of the major axis to the thickness) of not less than 5, and a ratio of the minor axis to the major axis, of from 1 to 10, and having the shape of a leaf as a whole. This powder can be prepared by melting a metal or glass, bringing the resulting melt to flow out from a nozzle and jetting a gas to the melt to form droplets of the melt, and bringing said droplets, before they solidify, to collied against the surface of a rotating cooling member having the shape of an cone or horn and provided in the directio of the flow of said droplets, followed by cooling to effect solidification. This powder can readily cause the leafing phenomenon when added in coating materials and coated, and hence the coating surface can be effectively covered with the powder, so that it can impart superior corrosion resistance and weathering resistance as compared with conventional powders. It can also impart superior electromagnetic shielding properties when added in plastics or rubbers.
