Abstract [en]

Elastic constants of disordered refractory Ru100-xMexAl alloys are calculated from first principles using a density-functional-theory based exact muffin-tin orbitals method combined with a coherent potential approximation. As alloying elements we considered Me = Ni, Co, Ir and Fe. We have found that peculiarities in the concentration dependencies of elastic constants on alloying metals content depend on their position in the Periodic Table with respect to Ru. These peculiarities can be connected with the changes in the electronic structure which take place upon alloying.
