Novel FeMnCoCrAl high entropy alloy family is introduced for the first time.
- class="label">•
Single BCC phase solid solution form at equiatomic and non-equiatomic compositions.
- class="label">•
Ab-initio predictions of BCC phase stability agree with experiments.

Equiatomic thin film and as-cast bulk HEA exhibit similar structure and properties.
- class="label">•
Combinatorial alloy design approach would enable accelerated exploration of HEAs.
