Fracture Mechanisms in High-Cycle Fatigue of Selective Laser Melted Ti-6Al-4V

Abstract:

Selective laser melting (SLM) is an attractive metal additive manufacturing technique that can create functional finished components. The microstructure that originates from SLM, however, differs in many aspects from that obtained from conventional manufacturing. In addition, the microstructure-mechanical properties relationship is not yet fully understood. In this research, the high-cycle fatigue performance of SLM Ti-6Al-4V was studied. The dominant fracture mechanisms were reported and discussed in relation to the microstructure of the specimens.
