Abstract
A hybrid cast component (10) including both a columnar grained region (12) and a single crystal region (14) integrally formed and joined along a metallurgical boundary (32) in a single casting operation without the need for any weld or braze. A gas turbine blade formed as such may include a columnar grained airfoil and a single crystal platform without any necessity for a thermally formed joint at the blade fillet area.
