Defect generation and propagation mechanism during additive manufacturing by selective beam melting
TL;DR: In this article, a mesoscopic numerical model based on the Lattice Boltzmann Method for the local melting process was developed for individual powder particles, taking into account full hydrodynamics including capillary and wetting effects.

Processing window and evaporation phenomena for Ti–6Al–4V produced by selective electron beam melting
TL;DR: In this article, the processing window for additive manufacturing by selective electron beam melting is determined for a wide range of scanning speeds and line energies, and the influence of the energy input on the resulting heat-affected zone and alloy composition is discussed.

Evaporation model for beam based additive manufacturing using free surface lattice Boltzmann methods
TL;DR: In this article, an evaporation model for beam-based additive manufacturing processes, such as selective electron beam or selective laser melting (SEBM/SLM), is presented.

TL;DR: In this paper, the lifetime, width and depth of the pools of molten powder material are analyzed for different beam powers, scan speeds and line energies in experiments and simulations, and a thermal finite element simulation tool is used to simulate the temperature distribution in the selective electron beam melting process.
A combinatorial study on the influence of elemental composition and heat treatment on the phase composition, microstructure and mechanical properties of Ni–W alloy thin films
TL;DR: In this article, several Ni-W thin film gradients were synthesized by magnetron sputtering spanning the entire binary composition range, and the structure and phase composition were characterized by means of X-ray diffraction and transmission electron microscopy.
