Core Technology
Nanometallurgy
• Nanometallurgy is an emerging interdisciplinary field of materials science and engineering (especially metallurgy), manufacturing, nanoscience and engineering, studying how to design and apply nanophase (ex-situ and in-situ generation) to significantly improve processing/ Manufacturing process, micro/nano structure, and physical/chemical/mechanical behavior of metals and alloys.
• High-performance metals and alloys offer great potential to improve energy efficiency and system performance for many applications. Although the field of metallurgy has made great contributions to human civilization in the past few thousand years, traditional metallurgical methods have reached certain limits. The sudden emergence of nano metallurgy is gradually breaking the traditional metallurgical barriers and completely changing metal processing and manufacturing technology.
• With the rapid development of nanophase synthesis, addition and dispersion of large-scale manufacturing methods, the prices of metals and alloys produced by nano-metallurgy have become more and more competitive.
