Abstract

An alloy consisting of, in atomic percent: aluminium: 20 to 35%; zirconium: 16.7% or less; vanadium: 7% or less; tungsten: 35% or less; chromium: 35% or less; iron: 10% or less; nickel: 5% or less; titanium: 40% or less; tantalum: 35% or less; niobium: 20% or less; molybdenum: 35% or less; cobalt: 5% or less; manganese: 10% or less; copper: 5% or less; hafnium: 10% or less; silicon: 5% or less; platinum: 5% or less; palladium: 5% or less; ruthenium: 10% or less; rhodium: 5% or less; iridium: 5% or less; rhenium: 35% or less provided ARe≤(35−ATa)+(35−AW)+(20−ANb) and where ARe, ATa, AW and ANb are the amounts in atomic percent of rhenium, tantalum, tungsten and niobium respectively; and incidental impurities less than 1 at % in sum; wherein the following equations are satisfied where xi is the atomic fraction of element i in the alloy, VECi is the number of valence electrons associated with an atom of element i and R is the universal gas constant.
