Abstract

High strength, heat resistant aluminum-based alloys have a composition consisting of the following general formula Al.sub.a M.sub.b X.sub.d or Al.sub.a' M.sub.b Q.sub.c X.sub.d, wherein M is at least one metal element selected from the group consisting of Co, Ni, Cu, Zn and Ag; Q is at least one metal element selected from the group consisting of V, Cr, Mn and Fe; X is at least one metal element selected from the group consisting of Li, Mg, Si, Ca, Ti and Zr; and a, a', b, c and d are, in atomic percentages; 80.ltoreq.a.ltoreq.94.5, 80.ltoreq.a'.ltoreq.94, 5.ltoreq.b.ltoreq.15, 0.5.ltoreq.c.ltoreq.3 and 0.5.ltoreq.d.ltoreq.10. In the above specified alloys, aluminum intermetallic compounds are finely dispersed throughout an aluminum matrix and, thereby, the mechanical properties, especially strength and heat resistance, are considerably improved. The aluminum-based alloys of the present invention are very useful as light-weight, high-strength materials, namely, high specific strength materials, both at room temperature and elevated temperatures.
