摘要： Superplastic forming of aluminum work stock is improved by including therein about 0.05% to about 10% or 15% scandium together with up to 0.2 or 0.25% zirconium. In preferred practices, soluble elements such as magnesium are also included in the aluminum alloy. One or more of the elements from the group of scandium, yttrium, gadolinium, holminum, dysprosium, erbium, ytterbium, lutetium, and terbium, may be included in addition to or in lieu of scandium. Heat treatable aluminum alloys such as 7XXX alloys and 2XXX alloys can be made superplastic by including scandium and zirconium to provide very high strength in superplastically formed products.

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.
