Abstract
A method for manufacturing a blade, the method includes casting a nickel alloy blade precursor having an airfoil and a root. The airfoil and the root are solution heat treating differently from each other. After the solution heat treating, the root is wrought processed. After the wrought processing, an exterior of the root is machined.
Claims20
A method for manufacturing a blade, the method comprising:
- casting a nickel alloy blade precursor having:
- an airfoil;
- and
- a root;
- solution heat treating the airfoil and the root differently from each other;
- after the solution heat treating, wrought processing of the root;
- and
- after the wrought processing, machining an exterior of the root,
- wherein the solution heat treating provides the root with larger average gamma prime size than the average gamma prime size of the airfoil.
