Abstract: An investment mold includes a refractory investment wall that has a surface region that bounds at least a portion of a mold cavity for receiving a molten metallic material. At least a portion of the surface region includes at least one metallic donor element with respect to the molten metallic material. Upon exposure of the surface region to the molten metallic material, the metallic donor element dopes into the molten metallic material. The method can be used to fabricate a cast article. The cast article can include a body formed of a metallic material having at least one reactive metallic element with respect to reactive-element-loss in an investment casting process. The body can include at least one internal passage that has a surface region that is compositionally rich in the reactive metallic element, which is doped into the body from the surface region of the refractory investment wall.

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.

Abstract: A method of making a composite core includes forming first and second cores of refractory metal and ceramic material. Each of the first and second cores is formed with two layers of a material. The layers are bonded together to form a laminate master pattern, and a flexible mold is formed around the pattern. The pattern is removed from the flexible mold, and slurry material, either pulverulent refractory metal material or ceramic material, is poured into the flexible mold. The slurry material is sintered to form each core. The first core is used as an insert while making the second core to create a final composite core.
