1. A method of making a single-crystal turbine blade with a material having a face centered cubic crystallographic structure, the method comprising:
during manufacturing of the single-crystal turbine blade:
controlling a secondary crystallographic orientation of the material based on a parameter of a root fillet between an airfoil of the single-crystal turbine blade and a platform of the single-crystal turbine blade;
controlling a primary crystallographic orientation of the material to be at 30 degrees from an airfoil stacking line of the single-crystal turbine blade; and
controlling the secondary crystallographic orientation of the material to be perpendicular to a reference plane that is perpendicular to an edge of the root fillet, the edge of the root fillet being closer to the airfoil than to the platform.
