    Abstract: A crankshaft for an internal combustion engine is provided. The crankshaft comprises at least four main journals aligned on a crankshaft axis of rotation defining a centerline. The crankshaft further comprises at least three pin journals. Each pin journal is disposed about a respective pin journal axis and positioned between the main journals. Each of the pin journals is joined to a pair of crank arms. Each pair of crank arms is joined to a respective main journal. Each of the main journals, pin journals, and crank arms is made of a first metallic material. Each crank arm has an over-molded counterweight metallurgically bonded thereto. Each counterweight is disposed opposite a respective pin journal relative to the centerline for balance and stability. Each counterweight is made of a second metallic material. The crankshaft has a weight ratio of the second metallic material to the first metallic material of between 0.20 to 0.50.

    Abstract: A method to make a stator lamination of an axial flux motor for an automobile vehicle includes: constructing a stator having multiple stator stack members, including: providing a stator lamination with individual ones of the stator stack members; forming the stator lamination from a single lamination sheet of steel defining a sinuous-shaped assembly having multiple bends; compressing the stator lamination; and machining the stator lamination to create a first edge by removing a first portion of the multiple bends and to create a second edge opposite to the first edge by removing a second portion of the multiple bends.

    Abstract: High-strength, lightweight alloy components, such as automotive components, capable of high temperature performance comprising aluminum, silicon, and iron and/or nickel are provided, along with methods of making such high-strength, lightweight alloy components. A high-energy stream, such as a laser or electron beam, may be selectively directed towards a precursor material to melt a portion of the precursor material in a localized region. The molten precursor material is cooled at a rate of greater than or equal to about 1.0×105 K/second to form a solid high-strength, lightweight alloy component comprising a stable ternary cubic phase having high heat resistance and high strength. The stable ternary phase may be AlxFeySiz, where x ranges from about 4 to about 5 or about 7.2 to about 7.6, y is about 1.5 to about 2.2, and z is about 1. The stable ternary phase may also be Al6Ni3Si.
