摘要：
A core-in-a-core casting method and hybrid core (40) for use in the method. An inner core (42) formed of process-inert particles disposed in a binder material is used as a mold for casting an outer core ((44) formed of particles that will sinter during a subsequent firing step. The inner core provides mechanical support for the outer core during the firing step, and during which the inner core devolves into compacted but unbonded particles that can be removed conveniently from the outer core following the firing step to reveal the fired hollow outer core (44).
