SUPERALLIAGES A BASE DE NICKEL POUR PRODUIRE DES PIECES A STRUCTURE MONOCRISTALLINE, PIECES AINSI OBTENUES, ET PROCEDES DE TRAITEMENT THERMIQUE ASSOCIES

Gas turbine engine efficiencies are increased through improvements in nickel-base superalloys used to make parts and components for gas turbine engines. These improved superalloys consist essentially of, in percentages by weight, 5-10 Or, 5-10 Co, 0-2 Mo, 3-10W. 3-8 Ta, 0-2 Ti, 5-7 Al, 0-6 Re, 0-0.5...
