An alloy and a gas turbine engine component comprising an alloy are presented, with the alloy comprising:

• palladium, in an amount ranging from about 1 atomic percent to about 41 atomic percent;
• platinum, in an amount that is dependent upon the amount of palladium, such that
  • a. for the amount of palladium ranging from about 1 atomic percent to about 14 atomic percent, the platinum is present up to about an amount defined by the formula (40+X) atomic percent, wherein X is the amount in atomic percent of the palladium, and
  • b. for the amount of palladium ranging from about 15 atomic percent up to about 41 atomic percent, the platinum is present in an amount up to about 54 atomic percent; and
• the balance comprising rhodium, wherein the rhodium is present in an amount of at least 24 atomic percent;

  wherein the alloy comprises a microstructure that is essentially free of L12-structured phase at a temperature greater than about 1000 C.
