  • Multi-Shot Casting
    Publication number: 20170259330
    Abstract: An alloy part is cast in a mold (280) having a part-forming cavity (292, 294, 296). The method comprises pouring a first alloy into the mold. The pouring causes: a surface (550) of the first alloy in the part-forming cavity to raise relative to the part-forming cavity; a branch flow of the poured first alloy to pass upwardly through a first portion (304) of a passageway; and the branch flow to pass downwardly through a second portion (310), of the passageway; solidifying some of the first alloy in the passageway to block the passageway while at least some of the first alloy in the part-forming cavity remains molten. A second alloy is poured into the mold atop the first alloy and solidified.

    Patent number: 9545664
    Abstract: A high-temperature die casting die includes a first die plate with a first recess and a second die plate with a second recess, the first and second recesses defining a main part cavity and gating. A grain selector is in fluid communication with the main cavity, and an in situ zone refining apparatus is adapted to apply a localized thermal gradient to at least one of the first and second die plates. The localized thermal gradient and the at least one die plate are movable relative to each other so as to apply the localized thermal gradient along a first direction extending from the grain selector longitudinally across the main part cavity.
