Abstract

The problem of healing of microscopic pores and cracks in the temperature field and understatic and dynamic pressures attracts considerable attention. Indeed, regeneration of continuity leads to a significant improvement of physical and mechanical properties of the materials where micropores were formed as a result of long—term loading (high—temperature creep, fatigue), surface deformation (friction, wear, grinding), specialconditions of processing (casting, powder metallurgy, condensed films) [1– 10]. For instance, the elimination of porosity allows longer lifetimes [1– 7] and higher ultimate strength [8], elastioonstants [91], and also electric and magnetic properties [10]to be achieved.
