Abstract

ARRANJO DE UMA LIGA À BASE DE NI, UM COMPONENTE E UMA TURBINA A GÁS E USO DE PD EM CONEXçO COM TAL LIGA. A presente invenção refere-se a uma liga à base de Ni adequada para componentes únicos cristalinos solidificados direcionalmente ou componentes policristalinos para serem usados em altas temperaturas. A liga é uma liga y'Iy e consiste em diferentes elementos de ligação dentro de faixas definidas. Entre outras faixas definidas de elementos, a liga contém Pd em uma quantidade significativa suficiente para guarnecer a liga com uma resistência 10 melhorada contra a fragilização do hidrogênio. A invenção também refere-se a um componente (13, 15) projetado para uso como componente (13,15) em um ambiente de alta temperatura. Além disso, a invenção 15 se refere a um arranjo de turbina a gás. Além disso, a invenção se refere ao uso de Pd para fornecer uma liga com resistência melhorada contra a fragilização do hidrogênio.ARRANGEMENT OF A NI BASED ALLOY, COMPONENT AND GAS TURBINE AND USE OF PD IN CONNECTION WITH SUCH ALLOY. The present invention relates to a Ni-based alloy suitable for directionally solidified crystalline single components or polycrystalline components for use at high temperatures. The alloy is a y'Iy alloy and consists of different connecting elements within defined ranges. Among other defined ranges of elements, the alloy contains Pd in a significant amount sufficient to provide the alloy with improved resistance to hydrogen embrittlement. The invention also relates to a component (13,15) designed for use as component (13,15) in a high temperature environment. Furthermore, the invention relates to a gas turbine arrangement. Furthermore, the invention relates to the use of Pd to provide an alloy with improved hydrogen embrittlement strength.
