| Abstract: | Abstract Superaltoys are multi-component alloys containing many alloying additions developed for high temperature applications. Refractory metals are added to impart beneficial properties to the alloy. The role refractory metal additions in precipitation processes in superalloys are discussed in this paper. The minor variation in the alloying additions on the changes in precipitation behaviour are illustrated with the example of Alloy 718 and Alloy 625. |
