摘要： Targets for the fabrication of quasicrystalline films are prepared from powders of the elemental constituents of the objective quasicrystalline material that have been pressed into a required target shape. The temperature of target fabrication is maintained sufficiently low that quasicrystalline alloy formation does not occur during target fabrication. Due to the high thermal shock resistance of each of the individual constituents and due to the dispersed form of the powders comprising the target, the target demonstrates very high resistance to thermal shock.

摘要： A process for producing an amorphous alloy material characterized by imparting ductility to an amorphous alloy having a supercooled liquid region by giving a prescribed amount of strain at a prescribed strain rate to the alloy in the glass transition temperature region of the alloy. The amorphous alloy may be in the form of spherical or irregular-shaped powders or thin ribbons or in the form of primary consolidated shapes thereof or an amorphous alloy casting. The amount of strain and strain rate are preferably 50% or greater and 2.times.10.sup.-2 /sec or higher, respectively, and the worked amorphous alloy material is preferably allowed to cool in a furnace or spontaneously. Suitable examples of the amorphous alloy to be employed include Al-TM-Ln, Mg-TM-Ln, Zr-TM-Al and Hf-TM-Al alloys, wherein TM is a transition metal element and Ln is a rare earth metal element. The thus obtained amorphous alloy is greatly improved in the prevention of embrittlement in hot working peculiar to the alloy.

C. and at a rate ranging from 0.00021 m/sec to 0.00001 mm/sec, to improve the formability thereof and allow forming to be conducted at lower temperature. The rapidly solidified magnesium based alloy has a composition consisting essentially of the formula Mg.sub.bal Al.sub.a Zn.sub.b X.sub.c, wherein X is at least one element selected from the group consisting of manganese, cerium, neodymium, praseodymium and yttrium, "a" ranges from 0 to about 15 atom percent, "b" ranges from 0 to about 4 atom percent and "c" ranges from about 0.2 to 3 atom percent, the balance being magnesium and incidental impurities, with the proviso that the sum of aluminum and zinc present ranges from about 2 to 15 atom percent. Such an alloy contains fine grain size and finely dispersed magnesium-, aluminum- rare earth intermetallic phases. When formed, the part exhibits good corrosion resistance together with high ultimate tensile strength and good ductility at room temperature, which properties are, in combination, far superior to those of conventional magnesium alloys. The part is suitable for application as a structural member in helicopters, missiles and air frames where good corrosion resistance in combination with high strength and ductility is important.

摘要： A first die is filled with a mixed powder prepared by mixing a low-melting-point lubricant powder into a basic metal powder in a weight ratio of 0.1 to 0.2%. A first pressure is applied to the mixed powder in the first die to form a mixed powder intermediate compressed body having a true density ratio of 80 to 90%. The mixed powder intermediate compressed body is heated to the melting point of the lubricant powder. The heated mixed powder intermediate compressed body is placed in a second die that is pre-heated to the melting point of the lubricant powder. A second pressure is applied to the mixed powder intermediate compressed body in the second die to form a high-density mixed powder final compressed body.
