A turbine blade having a leading edge portion and a flowing-off edge portion is formed using the following steps: providing a centrifugal casting device having a rotor and at least one crucible being accommodated in the rotor; providing a mold having an extended cavity for forming the turbine blade; arranging the mold so that an inlet opening of the mold is arranged with an outlet opening of the crucible, and further arranging the mold so that a mold leading edge is directed in a direction against the rotational direction of the rotor; forcing a metal melt by means of centrifugal forces from the crucible into the mold; exerting a pressure on the melt being forced into the mold until the temperature of the solidifying melt has reached a predetermined cooling-temperature; and relieving the pressure when the temperature of the solidifying melt is below the predetermined cooling-temperature.
