originates from the AM process. To understand the effect of the microstructure on the tensile properties, selective laser melted (SLM) Ti-6Al-4V samples built in three different orientations were tensile tested. The investigated samples were near fully dense, in two distinct conditions, as-built and stress relieved respectively. It was found that the build orientation affects the tensile properties, and in particular the ductility of the samples. The mechanical anisotropy of the parts was discussed in relation to the crystallographic texture, phase composition and the predominant fracture mechanisms. Fractography and electron backscatter diffraction (EBSD) results indicate that the predominant fracture mechanism is 2 intergranular fracture along the grain boundaries present and thus provide and explanation for the typical fracture surface features observed in fracture AM Ti-6Al-4V.

YBCO films were prepared by pulsed laser deposition from nanocrystalline targets doped with different concentrations of BaZrO 3 ranging from c = 0.9 to 9.0 wt%. The critical temperature of the films decreases almost linearly with increasing BaZrO 3 content whereas the critical current density shows a maximum near 3.9 wt%. In comparison with undoped YBCO films the accommodation field B * is considerably enhanced and the critical current density is improved in high fields in the films doped with BaZrO 3 , e.g. for c = 3.9 wt% by factor of 4.5 in a field of 5 T at 5 K. In the doped films the BaZrO 3 particles grow epiaxially with YBCO. Transmission electron microscopy results show that the density of the BaZrO 3 particles increases with increasing doping but the particle size remains practically the same (5-10 nm).
