Role of molten pool mode on formability, microstructure and mechanical properties of selective laser melted Ti-6Al-4V alloy

Relative densities, microstructures, microhardness and tensile properties of single-track and cuboid Ti-6Al-4V samples produced by selective laser melting (SLM) are investigated to explore the effect of molten pool mode. Results show that molten pool mode acts a significant role in determining their formability, microstructure and mechanical properties. Molten pool experiences a transition from keyhole to conduction mode by varying scanning...
