摘要： A dispersion-strengthened aluminum alloy having a composite structure containing a matrix of .alpha.-aluminum and a precipitation deposited phase of an intermetallic compound with the intermetallic compound in a volume ratio of not more than 35 vol. %, has both high strength and high toughness. The precipitation phase of the intermetallic compound has an aspect ratio of not more than 3.0, the .alpha.-aluminum has a crystal grain size which is at least twice the grain size of the precipitation phase of the intermetallic compound, and the crystal grain size of the .alpha.-aluminum is not more than 200 nm. It is possible to obtain an aluminum alloy having the aforementioned limited structure by carrying out first and second heat treatments on gas-atomized powder containing at least 10 vol. % of an amorphous phase or a green compact thereof and thereafter carrying out hot plastic working.

Melt of copper and silver is cooled at a high cooling speed of 10.sup.5 .degree. C./s or higher. Alloy powder having a composition expressed by a chemical formula Cu.sub.x Ag.sub.1-x (where 0.80.ltoreq.X.ltoreq.0.99) is obtained. Also, a dispersion-type conductor is produced by dispersing 100 parts by weight of the alloy powder in between 5-100 parts by weight of a binder. Thus, the low-priced alloy powder and the dispersion-type conductor of high quality and high reliability can be obtained.

摘要： Deposition of a hard film of Ti--Si--N composite material on a substrate is carried out by using a source of evaporation possessing a composition of Ti.sub.a Si.sub.b (wherein "a" and "b" stand for atomic percentages respectively falling in the ranges of 75 at %.ltoreq.a.ltoreq.85 at % and 15 at %.ltoreq.b.ltoreq.25 at %, providing a+b=100 at %). Deposition is effected by a sputtering process or ion plating process in an atmosphere of an inert gas containing a nitrogen-containing reaction gas while controlling the feed rate of the reaction gas into a chamber in such a manner that the partial pressure of nitrogen is kept constant or varied continuously or stepwise. By this method, there can be obtained a film having fine TiN crystalline particles uniformly dispersed in the matrix phase of Ti--Si amorphous metal or a film of functionally gradient structure in which the ratio of fine TiN crystalline particles dispersed in the matrix phase increases continuously or stepwise in the direction of thickness of the film.
