摘要：
A method is provided for casting an article such as a blade having an attachment root and an airfoil, the airfoil having a proximal end and a distal end. The method includes introducing a molten alloy into a mold. A composition of the introduced alloy is varied during the introduction so as to produce a compositional variation.
