Highlights
-
Twinning-induced plasticity (TWIP) is activated in TiZrHfNb high entropy alloys.
-
Metastable BCC and cryogenic temperature are two prerequisites for triggering TWIP.
-
Hierarchical {332}twinning networks dominate the deformation process.
-
{112}twins tend to be activated inside primary {332}twin bands.
-
The strength-ductility can be regulated by adjusting the niobium content at 77 K.
