1 Introduction As a well-established manufacturing process for the production of metal composites [1], cold roll bonding (CRB) conventionally requires high degrees of rolling reduction. The threshold reduction needed for bond formation is largely affected by the usually used air environment, resulting in the presence of surface oxide layers and passivating impurities. Both are also limiting the range of combinable materials [2].

1 Introduction In the last two decades, high-entropy alloys (HEAs), also known as multi-principal alloys, have exhibited extraordinary mechanical properties such as the combination of high strength and ductility, wear resistance, and toughness.
