    摘要: Disclosed herein is a process for forming an amorphous alloy material capable of showing glass transition, which comprises holding the material between frames arranged in combination; and heating the material at a temperature between its glass transition temperature (Tg) and its crystallization temperature (Tx) and, at the same time, producing a pressure difference between opposite sides of the material, whereby the material is brought into close contact against a forming mold disposed on one side of the material. As an alternative, the forming mold is brought into close contact against the amorphous material in a direction opposite to the pressing direction for the amorphous material. By the above processes, precision-formed products of amorphous alloys can be manufactured and supplied at low cost. These formed amorphous alloy products can be used as mechanical structure parts and components of high strength and high corrosion resistance, various strength members, electronic parts, arts and crafts, original printing plates, or the like.

    摘要: A structural member is produced using starting powder consisting of composite particulates each containing AlN grain within its surface covered by an Al layer of a single crystal structure, and Al alloy particulates of a single crystal structure, and then by sintering the Al layers of the composite particulates with the Al alloy particulates. The Al layers and the Al alloy particulates of the single crystal structure have no dislocation fault, crystal grain boundary. etc., produced therein, and for this reason, they have a low chemical activity. Therefore, the Al layers and the like have a characteristic that they are extremely difficult to oxidize. This ensures that the Al layers and the Al alloy particulates can be reliably sintered to achieve the densification of the resulting structural member.

    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.
