Microstructure and Properties of AlCrCoNiCuFeх (х =0 – 2.0) High-Entropy Alloys
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 3
Abstract
AlCrCoNiCuFeх (x values in molar ratio, x = 0; 0,5; 1,0; 2) high-entropy alloys were prepared using a vacuum arc melting method. The effects of Fe addition on microstructure and mechanical properties were investigated. The alloys exhibit quite simple FCC and BCC solid solution phases. Copper tends to segregate at the interdendrite region and forms a Cu-rich FCC phase. The formation of BCC phases significantly increases the hardness level of the alloy system.
