Abstract: A ladle, process, and system for casting an aluminum-based alloy includes a casting ladle. The casting ladle includes a cup and the cup defines an opening. The ladle also includes an ultrasonic transducer including an end immersed in the cup, wherein the cup exhibits a first depth and the ultrasonic transducer is immersed in the cup at a second depth in a range of 5 percent to 100 percent of the first depth. An aluminum-based alloy melt is introduced into an opening of a casting ladle, an ultrasonic transducer immersed in the aluminum-based alloy melt is activated, and the aluminum-based alloy melt is transferred onto a casting surface.

Abstract: A cylinder head having a cast-in-place valve seat for an automobile vehicle includes a valve seat having an inner wall. At least one retaining feature integrally and homogeneously extends from the inner wall. The valve seat when positioned into a casting mold has the at least one retaining feature assisting in retaining the valve seat in the casting mold. A metal in a molten form is received in the casting mold. A cast component formed after cooling of the metal has the valve seat cast-in-place.
