Effects of minor Hf on high temperature stress rupture properties of high angle grain boundary in a Re-containing Ni-based bicrystal superalloy

Effects of minor Hf on high temperature stress rupture properties of high angle grain boundary in a Re-containing Ni-based bicrystal superalloy

Two bicrystal specimens containing high angle grain boundary (about 20 degrees) were prepared by seed crystal method. The effect of Hf on the as-cast, heat-treated grain boundary microstructure, composition and stress rupture properties under 1100℃/100MPa was investigated in Ni-based single crystal...
