- Abstract
- The effect of lithium addition was examined on the structure and the mechanical properties of metallic composite materials, prepared from the binary eutectic Al-5.7 wt.% Ni alloy by casting and isostatic extrusion. A small amount of lithium addition significantly increases the tensile strength. The beneficial effect of lithium addition is due to solid-solution hardening for materials with low lithium content, i.e. those with less than about 1.7 wt.%; in addition, precipitation hardening due to the formation of small spherical particles of delta '-Al/sub 3/Li phase in the aluminium matrix has an increased effect for materials of higher lithium content.
