Abstract: An at least two step heating process is used to strengthen the shell of an investment casting mold including a refractory metal core. The first stage (46) may occur under otherwise oxidizing conditions at a low enough temperature to avoid substantial core oxidation. The second stage (56) may occur under essentially non-oxidizing conditions at a higher temperature.

Abstract: In accordance with the present invention, a casting system is provided which broadly comprises a core (10) and a wax die (12) spaced from said core (10), a refractory metal core (14) having a first end seated within a slot (18) in the core (10) and a second end contacting the wax die (12) for positioning the core (10) relative to the wax die (12), and the refractory metal core having at least one of a mechanism for providing spring loading when closed in the wax die and a mechanism for mechanically locking the wax die to the core. The spring loading mechanism may comprise one or more spring tabs (20). The locking mechanism may comprise an end (32) of the refractory metal core (14') engaging a slot (34) in the wax die (12') (Fig 2).
