摘要
A method for manufacturing a TiAl alloy impeller (2) comprises a blank manufacturing step in which a blank (1) of the TiAl alloy impeller (2) is manufactured, the blank (1) having a shaft portion (10) and a plurality of vanes (20) ), and an additional work step in which an additional work is carried out on each of the wings (20) of the blank (1). A thickness of an outer edge (21) of the blade (20) of the blank (1) is set to be larger than a thickness (t2) of an outer edge (21) of each of the blades (20) of the TiAl alloy impeller (2) . In the additional work step, the additional work is carried out on a first surface of a section of the wing (20), which contains at least the outer edge (21), or on the first surface and a second surface of this section, so that the outer edge (21) of the To make the wing (20) thin.
