Notch effect on the fatigue behaviour of AlSi10Mg aluminium alloy obtained by additive manufacturing
The fatigue behavior of the aluminum alloy AlSi10Mg manufactured by laser powder bed fusion for as-build and residual stress relief conditions with different notch geometries will be studied in this work. The fatigue tests (R=0) are carried out, at ambient temperature and in load control mode. The main results showed that the stress relief heat treatment had a slight positive effect on the fatigue strength, and effectively relieved residual stresses. The presence of different notches decreased the fatigue life when compared to the specimens without notches. Also, a model based on SWT parameter was successfully applied to predict fatigue life.
