  • Ni Based Alloy, a Component, a Gas Turbine Arrangement and Use of Pd in Connection With Such an Alloy
    Publication number: 20080101981
    Abstract: The invention concerns a Ni based alloy suitable for single crystalline, directionally solidified or polycrystalline components to be used at high temperatures. The alloy is a ??/? alloy and consists of different alloying elements within defined ranges. Among other defined ranges of elements, the alloy contains Pd in a significant amount sufficient to provide the alloy with an improved resistance against hydrogen embrittlement. The invention also concerns a component designed for use as a component in a high temperature environment. Furthermore, the invention concerns a gas turbine arrangement. Moreover, the invention concerns the use of Pd for providing an alloy with improved resistance against hydrogen embrittlement.
