  • GRAIN MICROSTRUCTURE IN DAMPERS OF GAS TURBINE ENGINE
    Publication number: 20140356150
    Abstract: A damper for a gas turbine engine is provided. The damper comprises a first portion, a second portion, and a surface. The second portion angularly extends from the first portion to define an interior corner therebetween. The surface bounds the first portion, the second portion, and the interior corner. The damper further comprises a grain composition containing columnar grains and equiaxed grains. The equiaxed grains are disposed adjacent to the surface such that a volume of the columnar grains is less than a volume of the equiaxed grains in the grain composition.
