Effect of Ti additions on mechanical properties of NbMoTaW and VNbMoTaW refractory high entropy alloys
TLDR
In this paper, a new refractory high entropy alloy (HEA) of TiNbMoTaW was developed, which possesses single body-centered cubic (BCC) phase structure, and could sustain the phase structure even after annealing at 1200°C for 24h.About:

Metastable high-entropy dual-phase alloys overcome the strength–ductility trade-off
TL;DR: In this metastability-engineering strategy, a transformation-induced plasticity-assisted, dual-phase high-entropy alloy (TRIP-DP-HEA) is designed, which combines the best of two worlds: extensive hardening due to the decreased phase stability known from advanced steels and massive solid-solution strengthening of high-ENTropy alloys.
