Abstract:
A die casting and a method for die casting a metal having a melting temperature of at least 1500° F. (815° C.) are disclosed. A molten volume of metal is injected to a casting die which includes a main cavity corresponding to an as-cast structure, a first reservoir, and a first runner arrangement. The first runner arrangement is configured to fluidly communicate molten metal between the first reservoir and the main cavity. After the injecting step, the casting die is sealed. The injected molten volume of metal is equiaxially solidified generally from a first portion of the main cavity distal to the first reservoir toward a second portion of the main cavity proximal to the first reservoir. During the equiaxial solidifying step, the main cavity is backfilled with at least a portion of the injected molten volume via the first runner arrangement.
