Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Effect of TiC on amorphous forming ability, microstructure, and thermal stability of Fe55Nb15Ti15Ta15 alloys

Fenmo yejin jishu
Due to the low amorphous forming ability and the poor room temperature plasticity, the engineering applications of Fe-based amorphous alloys were greatly limited. Based on the design concept of “near mixing enthalpy with effective atomic size difference”,
