Sažetak
The ability to customize the microstructure, surface morphology, and thus the mechanical properties of the widely used Ti6Al4V alloy, provoke great interest in the automotive, biomedical, and military industries, where high topological complexity of the final products with exceptional mechanical properties and minimal mass is often required. The use of selective laser melting (SLM), as one of the rapidly growing additive manufacturing technologies, represents a potential solution to this challenging task. Namely, by controlling the laser power and the scanning speed, the two most significant parameters of the SLM process, it is possible to influence the volume, type and shape of the voids inside material. However, even with similar porosity values, a difference in ductility can be observed. This suggests that the volume, type and shape of voids is not the only dominant mechanism affecting the mechanical behavior of these advanced materials. The different types of the martensitic microstructures created by the heating cycles during the SLM process, as well as the size and orientation of prior β-grain boundaries, also have a detrimental effect on the tensile properties. The aim of this work is to extend previous research findings of the influence of laser power and scanning speed on the microstructure, surface morphology, and behavior of these advanced materials under monotonic and cyclic loading conditions.
