Abstract: A method of casting a metal ingot with a microstructure that facilitates further working, such as hot and cold rolling. The metal is cast in a direct chill casting mold, or the equivalent, that directs a spray of coolant liquid onto the outer surface of the ingot to achieve rapid cooling.

Abstract: The performance and durability of compressor wheels coupled to turbocharger shafts are at odds with each other in that a higher rotational speed can be accommodated by an aluminum compressor wheel. But, aluminum has a low yield strength which causes the compressor wheel to expand outwardly at high rotational speeds such that the slip fit on the shaft no longer prevents wobble at high rotational speeds. To at least partially address this issue, the compressor wheel has two portions: an inner portion made of steel or titanium that has a relatively higher yield strength and a blade portion made of a lightweight, castable material. The inner portion is manufactured with grabbing features on its periphery, placed in a die, and the blade portion is cast over the grabbing features to yield a compressor wheel of two materials that provides sufficient shaft stiffening without high rotational inertia.
