The solidification microstructure due to Direct Laser Deposition (DLD) is known to be controllable using several process parameters that induce changes in the grain structure, micro-segregation, and phases present. This work focuses on a less investigated parameter, which is laser pulsing, investigating its ability to control the microstructure through studying the effect of different pulsing rates (10, 100, 1000 Hz) during thin wall powder DLD of IN718. The pulsing rate significantly affected the thermal history, meltpool shape, grain size and morphology, micro-segregation, and the presence of Nb-rich phases. Low pulsing rates appeared to remove the demarcation between the grain layers, while refining the grain size. Certain pulsing rates resulted in a less textured microstructure, compared with continuous wave DLD using the same process parameters (power, speed, and powder flow rate). Finally, the mechanical properties were also evaluated and a correlation between the metallurgical characteristics and the pulsing rate was established.
