摘要： Disclosed is a method of making lithium-containing aluminum base alloy extrusion having at least a section thereof having a low aspect ratio or which is generally axisymmetrical, the extrusions having improved properties in sections thereof having the low aspect ratio or which are axisymmetrical. The method comprises providing a body of a lithium-containing aluminum alloy, pressing a portion of the body which is to form the axisymmetrical or low aspect ratio section through a tortuous path and extruding an axisymmetrical or a low aspect ratio extrusion section. The axisymmetrical or low aspect ratio section of the extrusion has a tensile strength of at least 60 ksi and an ultimate yield strength at least 4.5 ksi greater than the tensile yield strength.

摘要： Disclosed is a method of producing an unrecrystallized aluminum alloy flat rolled product, e.g., plate or sheet, having improved levels of strength and fracture toughness. The method comprises the steps of providing a body of an aluminum base alloy, heating and hot working the body to a first product. This is followed by reheating, cooling and heat treating the first product prior to further working it to an unrecrystallized plate or sheet product, for example.

摘要： Composite materials having improved fracture toughness are formed by dispersing ductile inclusions in a less ductile matrix. The matrices may be formed from metals, such as high-strength aluminum alloys or ceramics. Bonding should be present between the inclusions and the matrix so that cracks in the composite material must pass through the inclusions.
