摘要: A turbine wheel (1) of an exhaust-gas turbocharger (2), formed from a titanium aluminide material, having a wheel back (7) which is of closed configuration as viewed from an axial direction (A) and which has an outer contour (17), a hub (3) which extends from the wheel back (7) and which tapers along the axial direction (A), and a multiplicity of turbine blades (4) which extend from the wheel back (7) and from the hub (3) and which blades extend outward in a radial direction (R), as far as a connection region outer diameter (DAB) at least in a connection region (5). The wheel back (7) has, in an outer region (11) adjoining the connection region (5), a wheel back outer diameter (DRR) which is greater than or equal to the connection region outer diameter (DAB).
