ABSTRACT:
A TiAl composition is prepared to have high strength, high oxidation resistance and to have acceptable ductility by altering the atomic ratio of the titanium and aluminum to have what has been found to be a highly desirable effective aluminum concentration by addition of chromium, niobium, and silicon according to the approximate formula Ti-Al.sub.45 Cr.sub.2 Si.sub.2 Nb.sub.4.
