- An analysis of the element distribution around the pores has yielded a deeper understanding of the homogeneity of the material before subjecting it to fatigue testing. These findings indicate that the material exhibits uniform properties across all orientations that have been studied.
- The sample manufacturing orientation directly influences its microstructure, as observed by a higher porosity with increased MPB. Notably, the 45° sample exhibited more MPB than the 0° and 90° samples, leading to a higher area and . These findings underscore the importance of accounting for the manufacturing orientation when characterising the microstructure of samples (Figure 12B and Figure 13).
- The fatigue behaviour of the specimens was evaluated by plotting the a/N curves of all samples. It was observed that the 45° sample tests exhibited a fairly inferior performance compared to the 90° and 0° tests. Specifically, the life span of the 45° specimens subjected to tests was found to be half that of the other two specimen orientations.
