Feature Article Title:
Cutting of Tantalum: Why It Is So Difficult and What Can Be Done About It
Feature Article Summary:
The 2021 Ekeberg Prize-winning paper by a US-Japanese research team investigates why tantalum is notoriously difficult to machine. Using high-speed imaging, it identifies sinuous plastic flow as the cause and demonstrates that applying a surface-adsorbing medium (e.g., permanent marker ink) transforms chip formation and improves machining efficiency.
- Tantalum-Niobium International Study Center (T.I.C.)
- The T.I.C. was established in response to concerns within the tantalum industry regarding the lack of useful information on tantalum source materials. The initial purpose of the T.I.C. was to spread information about tantalum and to promote the common interest and welfare of the producers, especially with public and private authorities, organisations and agencies. Since its foundation, the T.I.C. has grown to encompass niobium and all stages of the tantalum/niobium supply chains.
Advancing sustainability, technology, and industry collaboration since 1974.
