Fatigue crack initiation and propagation play an important role in fatigue properties, where they are shown to be strongly associated also with macroscopic residual stresses (RS). During additive manufacturing using the selective laser melting technology, a complex residual stress distribution is created that can significantly affect the printing itself and also the mechanical properties of...

Duplex stainless steels are grades composed primarily of α-Fe and γ-Fe phases. They exhibit better properties compared to single-phase steels and are widely used in many engineering areas. Shot peening is used to further improve the final properties of the materials. It is essential to know how this process affects the real structure. Using X-ray diffraction techniques, the impact of shot...

The paper deals with the analysis of residual stresses of additively manufactured AlSi10Mg alloy samples. The influence of the 3D printing strategy of the SLM (Selective Laser Melting) technology was proofed by X-ray diffraction. The phase analysis identified the intermetallic phase Mg2Si in addition to the major phases (solid solutions of Al and Si). The inhomogeneities of tensile residual...
