Selective laser melting of titanium alloy with 50 wt% tantalum : microstructure and mechanical properties

Selective laser melting of titanium alloy with 50 wt% tantalum : microstructure and mechanical properties

In this study, selective laser melting (SLM) was used to fabricate samples of titanium-tantalum (TiTa) alloy comprising 50 wt% of each element. Based on observation from scanning electron microscopy, as-fabricated samples comprised of randomly dispersed pure tantalum particles in a TiTa matrix. The...
