Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Titanium (Ti)–steel composite joints are prone to the formation of compounds such as TiC, TiFe, and TiFe2 during solid‐phase bonding. This phenomenon leads to premature failure and significantly reduces the bonding quality of the joints. However, the fracture behavior of the joint influenced by these compounds, particularly on the initiation ...
