Tensile properties of as-cast aluminum alloys AA3104, AA6111 and CA31218 at above solidus temperatures

The tensile mechanical response of three semi-solid as-cast aluminum alloys – AA3104, AA6111, and CA31218 (an alloy similar in composition to AA3003) – was measured between a fraction solid fs∼0.85 and fs∼1 in order to establish the mushy zone constitutive behavior under conditions similar to those believed to occur during direct chill (DC) casting. The fraction solid vs. temperature relationship for these alloys is also provided. The …
