Abstract
Multi-component vane segment and method for forming the same. Assembly includes: positioning a pre-formed airfoil component () and a preformed shroud heat resistant material () in a mold, wherein the airfoil component () and the shroud heat resistant material () each comprises an interlocking feature (); preheating the mold; introducing molten structural material () into the mold; and solidifying the molten structural material such that it interlocks the pre-formed airfoil component () with respect to the preformed shroud heat resistant material () and is effective to provide structural support for the shroud heat resistant material (). Surfaces between the airfoil component () and the structural material (), between the airfoil component () and the shroud heat resistant material (), and between the shroud heat resistant material () and the structural material () are free of metallurgical bonds.
