“Compositionally Complex Alloys – High Entropy Alloys (CCA-HEA)” (SPP 2006)
17 June 2020
Recently, a novel class of metallic alloys, referred to as “high entropy alloys” (HEA) or “compositionally complex alloys” (CCA), has been introduced. These alloys consist of near-equiatomic concentrations of multiple metallic elements. As such, they fundamentally differ from conventional alloys, which commonly consist of a primary element with additions of secondary (alloying) elements in order to achieve desired properties. This new concept of alloy design with no base element opens up a huge multi-component space with significant technological potential and poses challenging scientific questions.
The Senate of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has established the Priority Programme “Compositionally Complex Alloys – High Entropy Alloys (CCA-HEA)” (SPP 2006). The programme started in 2017 and is designed to run for six years.
