The chemistry, thermodynamics and mechanical properties of the L12-ordered Co3(Al,W) γ’-phase are crucial for the understanding of γ(f.c.c.)/γ’(L12) cobalt-based superalloys. A single-phase γ’(L12) alloy with the composition Co-30Ni-11Al-5.

Nickel- and cobalt-based superalloys derive their excellent oxidation and corrosion resistance from the surface oxidation of Al and Cr, which form protective oxide layers. Starting from an existing Cr-free cobalt-based superalloy (Co–30Ni–7Al–4
