A diffusion barrier type coating with a duplex layer structure, an inner r-(Re, W, Cr, Ni) as a diffusion barrier and outer Ni-aluminide as an Al reservoir, was formed on a Nickel based, single crystal, superalloy (TMS-82 +) and on Hastelloy X. Oxidation properties of both the alloys with or without
## Abstract The effect of crystal orientation on the microstructure of a nickelβbased crystalline superalloys during directional solidification was explored. Differently oriented crystals with [001] and [011] orientations were fabricated with seeding technique. The results showed that primary dendr
