    Abstract: A method for forming an airfoil includes forming a ceramic core, forming a refractory metal core using additive manufacturing, joining the ceramic core and the refractory metal core to form a hybrid core, and casting the airfoil around the hybrid core. The ceramic core is used to define an internal cavity of the airfoil. The refractory metal core has an upstream end and a downstream end. The upstream end has a lateral thickness greater than a lateral thickness of the downstream end. The refractory metal core is used to define a trailing edge cavity within the airfoil. The trailing edge cavity is in flow communication with the internal cavity of the airfoil and trailing edge slots located on an outer surface of the airfoil near a trailing edge. This method provides for an airfoil having a trailing edge cavity of variably thickness and casting cores used for their manufacture.

    Abstract: A method for manufacturing a railcar coupler knuckle includes, before casting, positioning an external chill within a cope mold portion and a drag mold portion offset from and adjacent internal walls of a pulling face and a throat of the cope and drag mold portions, thus producing a casting with reduced micro-shrinkage in at least the throat, a high-stress section of the casting. Use of subsurface chills produces an improved surface with fewer inclusions when compared to an equivalent surface produced in a process without use of a subsurface chill. The external chill may be a cone chill of a larger size to improve cooling and solidification at and below the surface. The external chill may also be a cylindrical and/or oblong chill with a tapered design that may correspond to the internal walls of the cope and drag mold portions between the pulling face and the throat.

    Abstract: A method of manufacturing a venturi tube (10') having a certain fluid flow direction is provided. The method provides a first core member (11) in a mold. The first core member has a periphery and an end (21) of a certain size. A second core member (17) is provided in the mold upstream of the first core member. The second core member has a periphery and an end (22) with a size that is less than the certain size. At least a portion of the end of the second core member (17) is disposed adjacent to at least a portion of the end of the first core member (11) such that a step is defined between the first and second core members. Material is molded about the peripheries of the first and second core members such that the peripheries define a stepped fluid flow surface of a venturi tube, and so that any resulting flash occurs only in the certain flow direction.
