The present work concerns the influence of surface (machined, as-built) on the fatigue resistance of AlSi10Mg produced by a powder-bed laser process. The competition between defects and surface roughness is assessed by using Kitagawa-type diagrams. S

The objective of the paper is to evaluate the impact of the morphology and the position of a casting defect on the fatigue limit of cast Al–Si alloy. Natural defects such as shrinkages reveal relatively complex morphology so the question is to unde

International audience; The Direct Current Potential Drop method is commonly used to monitor the crack growth during fatigue test when optical access to the crack is not possible. The reliability of this method depends on the calibration curve, which
