| Résumé: | Заглавие с экрана Changes of the surface roughness, microstructure, phase composition and microhardness of selective laser melting Ti-6Al-4V samples during electron beam irradiation and ultrasonic impact treatment were investigated by contact profilometry, optical microscopy, X-ray analysis, and hardness measurement. It was shown that electron beam irradiation and ultrasonic impact treatment of the selective laser melted Ti-6Al-4V samples smooth their surface. Significant refinement of the microstructure and TiO nanoparticles formation under ultrasonic impact treatment occur causing the increased surface microhardness. Electron beam irradiation intern leads to a more significant increase in both the microhardness and thickness of the melted surface layer due to martensitic transformation.
