Post Views: 23 1. Introduce – Second-generation single crystal superalloy with about 3% added Re * Single crystal superalloys Superalloy developed to increase creep resistance and temperature acceptance by minimizing the grain boundary The addition of grain boundary strengthening elements such as C, B, Zr, and Hf suppresses grain boundary formation and allows heat treatment at higher temperatures to increase the fraction of γ′ phase and improve microstructure uniformity Large amounts of refractory alloying elements such as W, Ta, and Mo are added to optimize the mechanical properties of ...
