Abstract: A blade (60; 60-2) comprises an airfoil (61) and an attachment root (63). The blade has a tipward zone (80; 80-2; 80-2, 81) and a rootward zone (82; 82-2, 81; 82). The rootward zone has a single crystal structure. The tipward zone has a single crystal structure. The crystalline orientations of the rootward zone and tipward zone are at least 15° out of registry with each other.

Abstract: A casting mold (260) comprises a shell (262) extending from a lower end (264) to an upper end (266) and having: an interior space (280) for casting metal; and an opening (268) for receiving metal to be cast. A plurality of thermocouples (900) are vertically-spaced from each other on the shell.

Abstract: A method comprises casting a metallic material (56) in a mold (20) containing a core, the core having a substrate (40, 44) coated with a coating (42). A removing the metallic material from the mold and decoring leaves a casting having a layer formed by the coating. The coating comprises a ceramic having a porosity in a zone (50) near the substrate less than a porosity in a zone (52) away from the substrate.
