Abstract/Summary Magnesium-aluminium. alloys, with varying content of aluminium from 0.5 to 12mass%, have been studied. With increase in aluminium content, the proof stress increased in two steps whereas the ductility exhibits correlated stepwise drops. The first increase in strength, and corresponding drop in ductility, are observed between 4 and 5 mass% Al. The second stepwise changes are observed between 10 and 12 mass% Al. These effects are connected with well defined changes in the microstructure: at 4.37 mass% small and large volume fraction of P-phase intermetallic particles appears in the core and surface regions, respectively along with eutectic network. At 11.6 mass% Al, the beta-phase interconnected network of intermetallics is developed at both die core and surface regions. The micromechanics of the strengthening and decrease in ductility are discussed.
