Symposium Scandium Extraction and Use in Aluminum Alloys
Sponsorship TMS Light Metals Division
TMS: Aluminum Committee
Organizer(s) Nigel Jeffrie Ricketts, Altrius Engineering Services
John F. Grandfield, Grandfield Technology Pty Ltd
Scope Scandium is a high impact alloying addition to aluminum having beneficial effects on several properties and in many aluminum alloy systems. However, the use of aluminum scandium alloys has been limited to low volume, special applications due to the high price of scandium. New sources of scandium are emerging with potentially lower costs in the form of new mines, red mud extraction, extraction from nickel ores and as a by-product of titanium pigment production. Papers on scandium extraction and use in aluminum alloy systems are sought for this symposium. Papers on the metallurgy of aluminium scandium alloy systems and applications are also required.

Session topics include:

- Scandium extraction including from red mud
- Aluminum scandium alloys (joint session with aluminium alloys symposium)
- Aluminum scandium alloys additive manufacture (joint session)
