Abstract Scope |
Titanium is defined as a critical raw material by the European Union and other entities due to its industrial importance as well as a current reliance on importations. Recycling titanium scraps can lead to strategic, economic and environmental gains.
One of the challenges, especially for applications such as aerospace, is the need to detect and remove critical defects such as inclusions. In titanium scrap these are generally classified as high-density (HDI) such as tungsten carbide tooling or low-density (LDI) such as oxides or nitrides.
A pilot-scale plasma-arc melter (PAM) with a multi-zone cold hearth crucible has been used to study these defects. First, numerical simulation was used to determine the residence time of the liquid flow. Melts were then deliberately seeded with HDI and LDI with analysis of the skull and ingot using various techniques in order to study the behavior of these defects. |
