  • Metallic article with integral end band under compression
    Patent number: 6893225
    Abstract: An article made of a metallic material and comprising a body and a body end portion integral with the body, includes a band of the metallic material at the end portion substantially through the entire end portion, the band being under a compressive stress greater than the body. An example of the article is a turbine engine balding member in which the body is the airfoil of the member and the band is disposed at the radially outer tip portion of the airfoil. One method for providing the band includes performing roller deformation on the end portion until a desired amount of compressive stress is developed in the band substantially through the entire end portion.
    Type: Grant

  • Turbine blade or turbine vane made of a ceramic foam joined to a metallic nonfoam, and preparation thereof
    Patent number: 6648596
    Abstract: A turbine blade or turbine vane includes a metallic nonfoam region, and a ceramic foam region joined to the metallic region. The ceramic foam region is an open-cell solid ceramic foam made of ceramic cell walls having an intracellular volume therebetween. The ceramic is preferably alumina. The intracellular volume may be empty porosity, or an intracellular metal such as an intracellular nickel-base superalloy.
