Název v původním jazyce
Impact of laser shock peening on fatigue strength of additively manufactured AlSi10Mg
Popis výsledku v původním jazyce
This study investigates the fatigue strength of additively manufactured AlSi10Mg under cyclic loading, focusing on the high cycle fatigue domain (HCF). Specimens were produced using Laser Powder Bed Fusion (LPBF), with the main objective of analysing fatigue strength concerning various post-processing surface treatments. The hourglass-shaped specimens were printed in a single batch, and six distinct groups of specimens were tested. Three series were left as-built, while three series were machined to achieve specific dimensions and surface roughness. Two setups of Laser Shock Peening (LSP) were applied for two groups of as-built specimens and two groups of machined specimens. Fatigue testing was conducted using a resonant pulsator. Surface roughness and residual stress depth profiles were analysed. Thermal response on the sample surface was monitored with an infrared thermal camera, enabling fatigue life prediction with fewer samples.
