Advanced Engineering Materials, EarlyView.Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot

Spatter Formation in Laser Welding with Beam Oscillation
Physics Procedia, 2013 AbstractThe investigation presented in this paper aims on a quantitative analysis of spatter formation in laser beam welding with superposed beam oscillation. After a discussion of design space limitations, which result from the scanner dynamics and theoretical considerations on the welding process itself, an optimal experimental design is created.

Advanced Engineering Materials, EarlyView.In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for
