Effect of Zr and B on castability of Ni-based superalloy IN792

The effect of Zr and B on hot tearing susceptibility of the Ni-based superalloy IN792 during directional solidification (DS) was studied. The Zr and B concentrations in the experimental alloys ranged from 0 to ~550 ppm. The results indicate that Zr or B does not influence the castability when added...
