Abstract

After solution treatment at 520 °C for 6 h and subsequent aging at 200 °C for 6 h, eutectic Mg2Si phase in Al-10%Mg2Si alloy transforms from long rod to short fiber-like and spherical morphologies, and a great number of nano-sized β″ particles precipitate in the Al matrix. The fine eutectic Mg2Si phase combined with nano-sized precipitates gives rise to enhanced hardness and high tensile strength of Al-10%Mg2Si alloy (increasing from 186 MPa to 234.6 MPa).
