The effects of ultrasonic impact treatment (UIT) on the microstructure and properties of the AlSi10Mg alloy manufactured by selective laser melting of powder are studied. Depending on the UIT duration, the evolutions of microhardness, surface morphology, residual stresses, strain extent, and structural–phase state of the AlSi10Mg-alloy specimens are analysed both directly after 3D printing and after preliminary T6 heat treatment (i.e., heating at 1°C/s, tempering for 1.5 h, water quenching, and artificial ageing at 150°C for 10 h). As proven, UIT can be recommended for post-processing of the 3D-printed products, as it is an effective method for improving the properties’ complex of the AlSi10Mg alloy owing to surface modification, namely: a microhardness increase above 4 GPa, the formation of macroscopic compressive stresses (up to −1380 GPa), and defectiveness reduction.
Key words: selective laser melting, thermal treatment, ultrasonic impact treatment, microstructure, phase composition, AlSi10Mg.
