Abstract: A process for casting a turbine wheel includes steps of identifying a metal composition from which the turbine wheel is to be cast, providing a mold that defines a cavity into which molten metal composition is to be poured for casting the wheel, providing a seed member made of the metal composition and having an equiaxed grain structure, disposing at least a portion of the seed member within the cavity of the mold, pouring the molten metal composition into the cavity such that the molten metal composition envelopes the portion of the seed member within the cavity, and controlling the process so that the portion of the seed member at least partially melts through contact with the molten metal composition and so that, upon cooling, the metal composition around the seed member solidifies with an equiaxed grain structure as precipitated by the equiaxed grain structure of the seed member.

Abstract: A method of manufacturing a directionally solidified article of the present disclosure includes providing a collection of particulate material and additively manufacturing a first article with an outer wall from the particulate material. The outer wall defines at least part of a cavity. The cavity contains an amount of the particulate material. The method also includes encasing at least a portion of the first article with an outer member. The outer member defines an internal cavity that corresponds to the first article. The method further includes heating the outer member and the first article to melt the first article into a molten mass within the internal cavity of the outer member. Additionally, the method includes solidifying the molten mass along a predetermined solidification path within the outer member to form a second article that corresponds to at least a portion of the internal cavity of the outer member.

Abstract: A process for making a turbine rotor includes steps of providing a shaft made of a first metal composition and having an integral pin projecting axially therefrom, providing a mold that defines a cavity for investment casting a turbine wheel, disposing the pin within the cavity of the mold, pre-heating the mold and the pin to a mold temperature, pouring a molten second metal composition into the cavity of the pre-heated mold such that the molten second metal composition envelopes the pin within the cavity, and controlling the process so that the pin acts as a chill member causing the second metal composition around the chill member to solidify with a finer equiaxed grain structure than would be the case without the chill member. The turbine wheel is joined to the shaft via the casting of the turbine wheel about the pin.
