Sparse Nanocrystals Enable Ultra‐Low Coercivity and Remarkable Mechanical Robustness in High‐Entropy Amorphous Alloy [PDF]

Advanced Science, Volume 12, Issue 38, October 13, 2025.
An order modulation strategy is introduced to overcome trade‐off between mechanical and magnetic properties by constructing an amorphous‐nanocrystalline transitional structure in a ferromagnetic HEA system. This enable the resultant alloys to combine an ultra‐low coercivity of 0.3 A m−1 with a remarkable mechanical toughness, thereby achieving a ...

Nanocrystallization in Fluorochlorozirconate Glass‐Ceramics [PDF]

Journal of the American Ceramic Society, 2013
Heat treating fluorochlorozirconate ( FCZ ) glasses nucleates nanocrystals in the glass matrix, resulting in a nanocomposite glass‐ceramic that has optical properties suitable for use as a medical imaging plate. Understanding the way in which the nanocrystal nucleation proceeds is critical to
