ABSTRACT:
Intermetallics capable of use as structural elements, exhibiting relatively high ductility and low brittleness, comprise ternary and quaternary TiAl.sub.3 alloys of the general formulae Al--Ti--M and Al--Ti--M--M', wherein M is selected from Cu, Ni, and Fe, M' is selected from V, Nb, and Ta. Such materials exhibit cubic, Ll.sub.2 crystal structures.
