Abstract: We have considered the effect of a helium medium during grinding of cement powder and rolling of polycrystalline aluminum on the number of water molecules and the kinetics of desorption of water from the surface of these materials during heating at a constant rate. We have separated the peaks on the water desorption curves and demonstrated the effect of the helium medium during fracture (grinding) and deformation (rolling) on the characteristics of desorption. The activation energies of water desorption in various temperature regions and their variation during fracture and deformation of materials in helium and in air have been estimated. It is proposed that helium atoms occupy sites vacant for adsorption of water molecules in the newly formed regions of bodies subjected to a mechanical action and that adsorbed atoms and molecules of the medium penetrate into the surface layer of the material in accordance with the mechanism of dislocation-dynamics diffusion (DDD).
