4 Conclusions

In order to investigate the role of primary dendrite arm spacing on mechanical properties of the Al–3wt%Cu–1wt%Li alloy, solidification experiments and tensile tests were carried out. The following main conclusions can be drawn from the present experimental investigation:

(1)The experimental expressions correlating the ultimate tensile strength and yield strength with primary dendrite arm spacing for an Al–3wt%Cu–1wt%Li alloy have shown that a finer structural dendritic morphology provides better mechanical properties than a coarser morphology; and
