The qualification of additive manufactured parts for large-scale applications, the understanding of microstructural formation and the correlation to properties is still insufficient. Laser metal deposition enables the use of conventional laser welding systems for the generation of additive products with high deposition and utilization rates. Due to beneficial creep and oxidation properties, Ti6Al2Sn4Zr2Mo is used in the present study. The deposition process is monitored with a high speed and an IR camera to improve the understanding of the deposition process and the emerging microstructure. Deposited layers are evaluated by visual and radiographic inspection, microstructural and gas analysis, hardness measurements and ex-situ tomography with regard to defects, microstructure and local mechanical properties. Deposition parameters are correlated to the microstructure and local mechanical properties. Besides, the relationship between microstructure and local mechanical properties is analyzed. Future work will also focus on the in-situ process monitoring and the consequential microstructure development.
