Titanium MMCs With Enhanced Specific Young’s Modulus via Powder Hot Extrusion
Abstract
In recent years, wire-based additive manufacturing has become an increasingly attractive manufacturing route for the production of large<br/>titanium components. However, only a few wire materials such as pure titanium and Ti-6Al-4V are commercially available, which are<br/>also prone to columnar grain growth leading to anisotropic mechanical properties. Further, there is a need to develop titanium components<br/>with high specific Young's modulus. To avoid anisotropy and increase the specific mechanical properties, there are two potential solutions:<br/>(1) the addition of alloying elements such as copper, which induce eutectoid reactions, and (2) the addition of ceramic particles with high<br/>intrinsic Young's modulus or the formation of intermetallic compounds, both of which can prevent grain growth and increase the overall<br/>Young's modulus of the composite. Therefore, we investigated the effects of adding different ceramic particles such as TiC and B 4C to<br/>titanium and titanium alloys. Since the reactivity between ceramics like B4C and titanium is known, the consolidation method must be<br/>carefully selected. One possibility is powder hot extrusion, by which a reaction may be effectively suppressed. However, powder hot<br/>extrusion is also a versatile tool to prepare different titanium alloys starting from elemental powders from the solid state. The resulting<br/>alloys and composites and their microstructure were experimentally investigated by optical microscopy and SEM, X-ray diffraction,<br/>microhardness, elastic modulus measurements with ultrasound and density. Furthermore, an increase in the specific Young's modulus<br/>could be observed in many particle-reinforced samples. It could be also demonstrated that reactive systems of ceramic particles and<br/>titanium can be effectively produced by powder hot extrusion.
