Abstract
A material and method for manufacturing components. The method includes squeeze casting the material into a component of a desired shape and flow-forming the component that has been squeeze cast to refine the shape of the component. The method also includes heat treating the component to enhance the microstructure of the component and machining the component to further refine the shape.
Claims10
A method for manufacturing components using an alloy material, said method comprising:
- providing an alloy material that includes 3-6 wt. % Si and 2-5 wt. % Cu+Mg+Zn;
- squeeze casting the material into a component with a shape having a first thickness, wherein the material is a liquid and is poured into a mold and cooled under pressure, and wherein squeeze casting the material includes cooling the component using cooling channels in a squeeze cast mold;
- treating the component with a T4 treatment;
- flow-forming the component that has been squeeze cast to refine the shape of the component;
- heat treating the component with a T5 treatment;
- and
- machining the component to further refine the shape and to create a component that is in final form.
