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: An investment casting pattern is formed by forming a metallic first core element (50) including at least one recess (34). The first core element (50) is engaged to at least a mating one of an element (60) of a die and a second core element. The recess (34) serves to retain the first core element (50) relative to the mating one. The die is assembled and a sacrificial material is introduced to the die to at least partially embed the first core element. The recess (34) may be pre-formed prior to cutting the first core element (50) from a larger sheet of material.

Abstract: Se proporciona un nucleo sacrificatorio para formar un espacio interior de una parte que incluye un elemento de nucleo ceramico y un primer elemento de nucleo que incluye un elemento de metal refractario. El elemento de nucleo ceramico se puede moldear sobre el primer elemento de nucleo se puede moldear con caracteristicas de ensamblado que permiten el ensamblado con el primer elemento de nucleo.
