title = "Effect of holding time on the microstructure of Mg-3Si-1.70Sn alloy during semisolid isothermal heat treatment",
abstract = "The microstructural evolution behavior of Mg-3Si-1.70Sn alloys during semisolid isothermal heat treatment was investigated by optical microscopy observations in the present study. With the holding time increasing, the grains evolve to be more spheroidal and 15min is adequate for the alloy to be spheroidized, after this coarsening begins to happen. The amount of the {"}liquid islands{"} inside α-Mg grains decreases and that of the liquid phase at the grain boundaries increases with the prolonged holding time. Moreover, the morphology of eutectic Mg2Si phases changes from the {"}Chinese script{"} and/or long-fiber shape to short fiber or spherical shapes during semisolid isothermal heat treatment, which can be attributed to the {"}Rayleigh shape instability{"}.",
