We are happy to congratulate our long-standing good colleague, now Dr.-Ing. Andre Riemer, for his highly successfully passed doctoral examination. The topic of the dissertation is ?Einfluss von Werkstoff, Prozessführung und W?rmebehandlung auf das bruchmechanische Verhalten von Laserstrahlschmelzbauteilen“ (engl.: Influence of material, process control and heat treatment on the fracture mechanical behavior of laser beam melting components).
