Semi-solid thermal transformations of Al−Si alloys and the resulting mechanical properties

This study demonstrated that 356/357 type Al−Si alloys cast with high solidification rates resulting in a fine grain structure could be rapidly thermally transformed into a structure suitable for semi-solid forming. The mechanical properties of these alloys were comparable to those of electromagneti...

Description
Summary:This study demonstrated that 356/357 type Al−Si alloys cast with high solidification rates resulting in a fine grain structure could be rapidly thermally transformed into a structure suitable for semi-solid forming. The mechanical properties of these alloys were comparable to those of electromagnetically stirred semi-solid as well as the as-cast properties.
