    IPC: C22C21/02

    Abstract: An enhanced aluminum alloy galvanically compatible with a magnesium alloy component is disclosed. The aluminum alloy comprises aluminum, less than 0.2 weight percent copper, less than 0.2 weight percent iron, 6.0 to 9.0 weight percent silicon, 0.6 to 1.5 weight percent magnesium, and greater than 0.8 weight percent manganese. The aluminum alloy further comprises less than 2 weight percent zinc, less than 0.1 weight percent nickel, less than 0.2 weight percent tin, less than 0.05 weight percent titanium; and 0.008 to 0.02 weight percent strontium. Manganese and iron have a weight ratio of at least 30:1. Furthermore, iron and manganese combined content is less than 2.0 weight percent.

    Abstract: According to aspects of the present disclosure, a method includes obtaining a first amount of magnesium, a second amount of manganese, and a third amount of a cathodic poison and combining the magnesium, the manganese, and the cathodic poison to thereby form a kinetically hindered magnesium alloy includes less than 1 part by weight of manganese and less than about 5 parts by weight of cathodic poison based on 100 parts of the kinetically hindered magnesium alloy. The cathodic poison is configured to inhibit a cathodic reaction when combined with the magnesium.

    Abstract: Presented are electronic power module assemblies with direct-cooling vapor chamber systems, methods for making/using such power module assemblies, and vehicles equipped with such power module assemblies. A power module assembly includes an outer housing with an internal coolant chamber that circulates therethrough a coolant fluid. A power semiconductor switching device is mounted to the module's housing, separated from the coolant chamber and isolated from the coolant fluid. The power device selectively modifies electric current transmitted between a power source and an electrical load. A two-phase, heat-spreading vapor chamber device includes an outer casing with a casing segment that is mounted to the module housing, fluidly sealed to the internal coolant chamber and exposed to the coolant fluid. Another casing segment includes an inboard-facing casing surface that is mounted to an outboard-facing surface of the power device, and an outboard-facing casing surface mounted to an inboard-facing surface of the power device.

    Abstract: Magnesium-aluminum corrosion-resistant alloys are provided and include magnesium, aluminum, germanium, small amounts of cathodic reaction active site impurities such as iron, copper, nickel, and cobalt, manganese, and optionally tin. The alloy can include up to about 0.75% germanium, at least about 2.5% aluminum, up to about 2.25% tin, at most 0.0055% iron impurities, and at most 0.125% silicon impurities. The ratio of germanium to iron can be less than 150. The ratio of manganese to iron can be at least 75. The alloy can comprise one or more intermetallic complexes, including magnesium-germanium, magnesium-aluminum, and aluminum-manganese internietallic complexes.
