Planar Front Growth of Single Crystal Ni-Based Superalloy René N515

Advancing Development and Application of Superalloys

“…This aspect is critical to the fabrication of single-crystal Ni-based superalloys and maximization of creep performance. Matsunaga et al 2 use planar front growth to reduce the density of porosity in alloy René N515 and avoid the formation of secondary phases. The chemical and structural homogeneity of the cast product is detailed experimentally and compared with thermodynamic predictions.…”
