Kurzfassung
The present study investigated the microstructure and tensile properties of titanium aluminide produced by SLM using prealloyed TNBV4-powder. The chosen factors were laser power, scan velocity of the laser, distance of the laser tracks (hatch space) and preheating temperature of the base plate. The effects of these parameters on porosity, shape of the samples, crack formation, chemical composition and microstructure were investigated with optical microscopy, XRF, scanning electron microscopy with EDS and EBSD and XRD.
