A high-entropy alloy (HEA) was applied to an alternative binder for the WC-Co cemented carbide as an attempt to seek enhanced mechanical properties. In the experiment, a CrMnFeCoNi HEA, which was the most well-known HEA, powder was used as a binder to fabricate WC-HEA cemented carbides by multi-beam laser directed energy deposition (L-DED).
