Effects on Microstructure and Mechanical Properties of the Addition of Co, Cr, and Fe to the Eutectoid System Ti-6.5Cu
Abstract
Wire-based additive manufacturing has increased in popularity for the fabrication of large titanium components. However,<br/>only a few wire materials (pure titanium and Ti-6Al-4V) are commercially available, and these are prone to columnar grain<br/>growth and, thus, anisotropic mechanical properties. Therefore, the primary objective was to develop titanium alloy wires<br/>with isotropic properties, high specific strength, and sufficiently high ductility after WAAM processing. Adding a eutectoid-<br/>forming alloying element like Cu or Ni can suppress the formation of columnar grains. Ti-6.5Cu-based alloys with Co, Cr<br/>and Fe additions in concentrations between 0.5 wt.% and 3 wt.% were first evaluated by CALPHAD methods and then<br/>experimentally prepared by inductive melting. Additionally, larger samples were produced by hot powder extrusion. The<br/>microstructural evolution was investigated by optical microscopy, scanning electron microscopy and X-ray diffraction.<br/>Further, the microhardness and tensile strength on selected samples were determined. Adding all elements leads to a<br/>martensitic microstructure, which refines upon the increasing amount of alloying elements. Furthermore, the addition of<br/>alloying elements leads to a reduction in the size of the prior β-grains and to equiaxial grain growth. In addition, an increase<br/>in mechanical properties was observed.
