It is shown that, when sputtered onto the surface of the (111) Ir face in the temperature range 1100-1250 K, beryllium atoms form a surface chemical compound of stoichiometry Ir3Be with a concentration of adsorbed beryllium NBe=5·1014 cm-2, after which the newly deposited beryllium atoms dissolve metal bulk. The Ir3Be surface compound itself is destroyed due to the dissolution of beryllium in the temperature range of 1250-1400 K with an activation energy increasing from 3.2 eV to 3.7 eV with decreasing Be concentration. At T>1400 K, the thermal desorption channel is switched on. The formation of the Ir3Be surface compound significantly lowers the energy barrier E for the dissolution of Be atoms in the bulk of iridium by Delta E>1.7 eV. Keywords: iridium, beryllium, surface chemical compounds, dissolution, bulk intermetallic compounds.
