In an axial-flow turbine consisting essentially of an outer casing, an inner casing with a preferably integrated vane carrier (5) and a rotor (3) fitted with rotor blades (6), the first stage is designed as a radial/axial stage. It is supplied with working medium from a toroidal or spiral inlet flow housing (4). The radial vanes (10) are provided at their two ends with root plates (14) by means of which they are bladed in annular recesses (15) in the blade carrier (5). The free end faces (19) of the root plates are of curved design.
