Steels in additive manufacturing: A review of their microstructure and properties (2020, background): “Stress relief heat treatments and HIP both have only a small effect on the fatigue performance, but largely, after surface finishing, the fatigue limit is in the range of conventionally processed samples [26,29,53].”
Design for Additive Manufacturing – Supporting the Substitution of Components in Series Products (2014, background): “The mechanical properties of metals processed by SLM exceed those of investment casting and almost reach those of wrought materials [2,6].”
