A Closed-Loop Recycling Technology for -TiAl from Precision Cast Low Pressure Turbine Blades

摘要

Due to the high generation of scrap in the process chain of -TiAl semi-finished goods and products, a suitable recycling process shows great potential to reduce production costs. Based on this circumstance, a closed loop recycling process for titanium-aluminide scraps was developed. Resulting from this process, as a significant innovation for the titanium industry, it is possible to recycle titanium-aluminide scraps and produce material with minimal oxygen content and almost no observable difference to primary alloys.
