The goal of these review papers is to summarize the recent advances in the metallurgy of aluminium alloys and from this analysis, to try to outline future developments in this field. Part I deals with the transformation of aluminium alloys from the liquid to the solid state, while Part II will focus on solid-state transformations. These papers are by no means exhaustive since the literature is very abundant, but the authors wish to give a personal view of what they think are the most relevant scientific contributions that can impact future technological developments.
