Superior Room Temperature to 750°C Strength‐Ductility Synergy in a B2‐Strengthened Ti50Al16.7Nb16.6V16.7 Lightweight Medium‐Entropy Alloy

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Lightweight refractory medium‐entropy alloys (LRMEAs) are promising for high‐temperature structural applications, yet achieving a robust strength‐ductility balance across a wide temperature range remains challenging. We report a Ti50Al16.7Nb16.6V16.7 (at.%) LRMEA featuring a BCC matrix reinforced by nano B2‐ordered domains, exhibiting ...
