    Abstract: Molten metal of a first composition is fed into a mold cavity, via a first control apparatus, wherein the control apparatus is open, wherein the feeding comprises flowing out of a first feed chamber. The first control apparatus is closed. A second control apparatus is opened. Molten metal of a second composition is fed into the mold cavity, via the second control apparatus, wherein at least a portion of the metal of the first composition in the mold cavity is sufficiently molten so that an initial feed of molten metal of the second composition mixes with the molten metal of the first composition in the mold cavity, wherein the feeding comprises flowing out of a second feed chamber, wherein the second composition is different from the first composition. An ingot is removed from the mold cavity, wherein the ingot has a top section, a middle section, and a bottom section, wherein the bottom section is composed of metal of the first composition, wherein the top section is composed of metal of the second composition, wherein the middle section is composed of a mixture of metal of the first composition and the second composition.

    Abstract: A fastener assembly for installation within a work piece, the fastener assembly including a bolt, a retainer ring, and a housing that houses the retainer ring. The housing is positioned at and engages one side of the work piece, while the bolt is inserted into a hole of the work piece on an opposite side thereof. The retainer ring engages the bolt such that a plurality of pressure pads extending from a plurality of corresponding spring beam elements of the retainer ring reside in an annular groove of the bolt. The housing captivates the bolt onto the work piece, while providing a positive hold out of the bolt.
