    Analýza stavu povrchu po shot peenovaní duplexnej ocele AlSi 318
    (University of Žilina, 2025) Neslušan, Miroslav; Florková, Zuzana
    This paper deals with surface integrity and the corresponding stress state as well as surface topography after shot peening of duplex steel AlSi 318 under the variable shot-peening conditions such as number of passes and applied air pressure. It was found that the energy of shot impacts is consumed mainly by austenitic phase whereas the ferritic one is less affected. High magnitude of residual stresses is developed under the higher number of cycles as well as for the higher media pressure. Amplitude of compressive residual stresses in austenite is more as that for ferrite one. Surface roughness is decreasing along with the number of shot peening cycles and the typical crater-like surface is produced.
