A Way to Estimate the True Surface Energy of Complex Metallic Alloys.

For the first time, to the best of our knowledge, a realistic approach for deriving an estimate by superior values of the surface energy of complex metallic alloys based on aluminium is proposed. It turns out that the surface energy of quasicrystals lies in the range 0.5–0.8 J/m2, in contrast to pure aluminium (1.15 J/m2) orλ-Al13Fe4(2.0 J/m2) andω-Al7Cu2Fe (2.2 J/m2) intermetallics.
