چکیده انگلیسی
A partial solution treatment was investigated to enhance the mechanical properties for a die-cast Al-Mg-Zn-Si alloy. The strengthening mechanism was identified that the Mg32(Al, Zn)49 intermetallics and equilibrium η-MgZn2 phase formed in the as-cast microstructure were partially dissolved into the α-Al matrix during solutionising and the fine semi-coherent η'-MgZn2 phase was precipitated during subsequent aging. Consequently, the unique microstructure was characterised by the co-existence of equilibrium η-MgZn2 phase and metastable η'-MgZn2 phase in the α-Al matrix, together with the un-changed Mg2Si eutectic and remnant Mg32(Al, Zn)49 intermetallics in the Al-Mg-Zn-Si alloy.
