  • Material for a gas turbine component, method for producing a gas turbine component and gas turbine component
    Patent number: 8888461
    Abstract: A material for a gas turbine component, to be specific a titanium-aluminum-based alloy material, including at least titanium and aluminum. The material has a) in the range of room temperature, the ?/B2-Ti phase, the ?2-Ti3Al phase and the ?-TiAl phase with a proportion of the ?/B2-Ti phase of at most 5% by volume, and b) in the range of the eutectoid temperature, the ?/B2-Ti phase, the ?2-Ti3Al phase and the ?-TiAl phase, with a proportion of the ?/B2-Ti phase of at least 10% by volume.
    Type: Grant

  • Method for producing a forging from a gamma titanium aluminum-based alloy
    Patent number: 8828160
    Abstract: Method for producing a forging from a gamma titanium aluminum-based alloy. The method includes heating at least a portion of a cylindrical or rod-shaped starting or raw material to a temperature of more than 1150° C. over a cross section of the at least a portion. The at least a portion corresponds to points at which the forging to be shaped has volume concentrations. The method also includes deforming the at least a portion through an applied force to form a biscuit having different cross sectional areas over a longitudinal extension of the biscuit, and finishing the forging through a second heating to a deformation temperature and at least one subsequent step.
