Description/Abstract | The development of aluminum-lithium metallurgy has led to alloys with unsurpassed combinations of density, specific strength, and specific modulus.^This paper describes recent advances in the modification of aluminum-lithium binary alloys through additions of the Group IV-A transition metals (titanium, zirconium, and hafnium).^These elements lead to a duplex precipitation hardening behavior through the formation of Al3Li and Al3(TM,Li) (TM = transition element) which act as strengthening precipitates.^The influence of the duplex structure on deformation mechanisms and the improvement of mechanical properties in these systems is illustrated by using results for the Al-Li-Zr system.^12 references. |
