Mechanical performance of additively manufactured (AM) Ti6Al4V scaffolds has mostly been studied in uniaxial compression. However, in real-life applications, more complex load conditions occur. To address this, a novel sample geometry was designed, tested and analyzed in this work. The new scaffold...

Similarly, a Gaussian process regression (GPR) model is used to predict the fatigue ratio of AM alloys with a 95% prediction interval. The Shapley Additive exPlanations (SHAP) method is used to explain the predictions of the GPR model. This framework is validated using Ti–6Al–4V, IN718, ...
Additively manufactured Ti-6Al-4V parts may show better mechanical properties than those of cast and wrought materials. However there are significant uncer

manufactured by Direct Metal Laser Sintering (DMLS). The surface properties before and after the UIT are characterized by surface porosity, roughness, hardness and residual stresses. Results show that UIT enhances the fatigue life of DMLS Ti-6Al-4V parts by suppressing the surface defects ...
One of the major obstacles facing full implementation of additive manufactured (AM) Ti-6Al-4V parts, however, is the concern with the reliability, especially under cyclic loading conditions. While extensive research has been conducted on the fatigue behavior of traditional wrought Ti-6Al-4V [5],...
