Summary

High thermal stability of precipitated phases is decisive for a reasonable stability of mechanical properties and for a good creep resistance up to high temperatures. Not only a volume fraction but also arrangement, orientation relationship and aspect ratio of precipitates affect mechanical and creep properties [1, 2]. It was proved that prismatic precipitate plates in a triangular arrangement play an important role in strengthening of WE54 alloy by providing effective barriers to gliding dislocations [3].
