Abstract

Optical metallography, transmission electron microscopy, and phase analysis were used to study the mechanisms of structural transformations in the surface layer of thickness Δ h ≈0.2 μm for single crystals and polycrystals of metals and alloys irradiated with high-power ion beams (HPIB's). Characteristic features of the formation of the surface relief and variations in phase constitution and defect substructure of pure metals (Ni, Mo) and single-phase (Mo-Re, Ni3Al) and double-phase (V-ZrO2) alloys have been found in relation to the ion beam power density Q =(1-10)×107 W/cm2. Common features and distinctions in the formation of the microstructure of metallic materials belonging to different classes under HPIB irradiation have been revealed. Based on the predictions of a numerical simulation of the time-dependent temperature fields and the melting and evaporation processes in the surface layer, the mechanisms for the phase-structure modification of metal and alloy surfaces are analyzed.
