Solid state phase transformations in aluminium alloys containing lithium

Abstract
The microstructure and solid state phase transformations which take place in aluminium alloys containing lithium have been assessed. In addition to the binary Al–Li system, the Al–Li–Cu, Al–Li–Mg, and Al–Li–Cu–Mg systems are discussed in detail together with the role of dispersoid forming elements. The physical metallurgical basis of current alloy development is thereby established. MST/595
