ABSTRACTVarious techniques of laser glazing are presented. Rules are given for the choise of systems which are suitable for producing amorphous surface layers. Methods of demonstrating the existence of a truly amorphous layer are discussed. Two examples are given: I) electron beam glazing of Ni-Nb coated single crystals 2) laser beam glazing of Fe-B coated Fe-Cr-C cold working steel.

Electron beam melting (EBM) is a direct metal additive manufacturing technique in which a 4 kW electron beam is utilized to manufacture the parts in a layer by layer fashion. This paper represents an investigation into the quasi-static compressive deformation behavior of EBM made specimens. The mechanical testing was carried out at strain rate of 10-3 s-1 by a numerically controlled hydraulic MTS machine on both as-built and machined samples manufactured by this high-tech process. The Vickers micro-hardness of the samples has been measured before and after the compression test. The microstructure of the compressed sample was characterized. The particle size distribution, morphology, and chemical composition of the Ti6Al4V, which is one of the most common materials for biomedical implants because of its high strength to weight ratio, corrosion resistance, and its biocompatibility features, have been investigated. The fracture surface has been characterized by scanning electron microscope.

Selective Electron Beam Melting (SEBM) is a powder bed-based additive manufacturing process for metals. As the electron beam can be moved inertia-free by electromagnetic lenses, the solidification conditions can be deliberately adjusted within the process. This enables control over the local solidification conditions. SEBM typically leads to columnar grain structures. Based on numerical simulation, we demonstrated how technical single crystals develop in IN718 by forcing the temperature gradient along a µ-Helix. The slope of the µ-Helix, i.e., the deviation of the thermal gradient from the build direction, determined the effectiveness of grain selection right up to single crystals.
