Abstract: An aluminum alloy according to the present invention includes from 4.0 to 6.0% Mg, from 0.3 to 0.6% Mn, from 0.5 to 0.9% Fe, and the balance of Al and inevitable impurities when the entirety is taken as 100% by mass. By appropriately selecting the composition range of Mg, Mn and Fe, it has been possible to micro-finely crystallize Al (Mn, Fe) compounds while inhibiting the growth of primary-crystal Al. As a result, the resulting aluminum alloy is good in terms of the castability, and shows high strength as well as high ductility.

Abstract: The invention provides a method of producing an oxidation-resistant metallic part which exhibits oxidation resistance even in an oxidation atmosphere. The method includes the step of applying mechanical energy to a surface of a metallic part in the presence of particulates, and forming a protective coating in a surface of the metallic part. When the metallic part thus treated is exposed in a high temperature-oxidation atmosphere, the protective coating is oxidized to restrain the proceeding of the oxidation of the metallic part, that is the internally proceeding formation of TiO2, thus serving a remarkable improvement of the oxidation resistance.

Abstract: The invention provides a method of producing an oxidation-resistant metallic part which exhibits sufficiently good oxidation resistance even in an oxidation atmosphere. The method includes the step of applying mechanical energy to a surface of a metallic part in the presence of particulates, and forming a protective coating in a surface of the metallic part. When the metallic part thus treated is exposed in a high temperature-oxidation atmosphere, the protective coating is oxidized to restrain the proceeding of the oxidation of the metallic part, that is the internally proceeding formation of TiO 2, thus serving a remarkable improvement of the oxidation resistance.
