The high-temperature application of high-entropy alloys (HEAs) fabricated via selective laser melting (SLM) relies on an in-depth understanding of the mechanical properties and deformation mechanisms involved. This study conducted tensile testing of FeCoCrNi HEA, at various temperatures and strain r...
