Abstract:
An alloy feedstock for semi-solid, metal, injection molding, said feedstock comprising:an aluminum alloy material in particulate form, said alloy material having a heterogeneous structure having a heat flow versus temperature curve with a heat flow temperature range of greater than 40.degree. C. when measured at 20% of the height of the peak of the main melting reaction, and having a heat flow ratio of less than 0.5 for the height of the peak of the eutectic reaction relative to the height of the main melting reaction, wherein said alloy material having said heterogeneous structure has a lower eutectic temperature than said alloy material with a homogeneous structure such that said alloy material having said heterogeneous structure forms a portion of the liquid phase below said eutectic temperature of said homogeneous structure.
