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.

摘要： A surface-coated cutting tool according to the present invention includes a base material and a coated film formed on the base material. The coated film serves as an outermost layer on the base material and has compressive stress. The compressive stress is varied so as to have strength distribution in a direction of thickness of the coated film. The strength distribution is characterized in that the compressive stress at a surface of the coated film continuously increases from the surface of the coated film toward a first intermediate point located between the surface of the coated film and a bottom surface of the coated film and the compressive stress attains a relative maximum point at the first intermediate point.
