| Abstract Scope |
Titanium scrap is highly recyclable but requires the addition of titanium sponge during vacuum arc remelting to achieve the desired properties. If the need for fresh sponge and re-melting could be eliminated during recycling, then energy consumption, carbon footprint, and sustainability could be dramatically improved. In this project, a solid phase processing methodology known as friction extrusion was used to recycle Ti-6Al-4V scrap into rods. Feedstock consisting of machining chips with varying oxygen levels was successfully extruded. Both optical and electron microscopy was used to investigate the evolved microstructures and to understand the breakage and distribution oxide particles. Additionally, the effect of intense strain and temperature on the microstructure evolution was discussed. To quantify the structural integrity of the rods, tensile testing, and hardness measurements were carried out. This investigation suggests friction extrusion as a potential pathway for recycling Ti-6Al-4V scrap without remelting or introducing fresh titanium sponge. |
