Formation of aluminides on Ni-based superalloy 690 substrate, their characterization and first-principle Ni(111)/NiAl(110) interface simulations

Ni-based superalloy 690 substrates were pack aluminized in a low Al-containing pack at 1273K for 4h in argon atmosphere. Scanning electron microscopy with energy dispersive X-ray analysis along the cross section of aluminized specimen revealed the formation of multilayer. The uppermost layer consist...
