Effect of Heat Treatment Temperature on Microstructure and Properties of FeCoNiCuTi High–Entropy Alloy

In the present work, FeCoNiCuTi high-entropy alloy (HEA) was heat-treated at different temperatures. After heat treatment at different temperatures, the crystal structure maintained its FCC + Laves phase structure. The saturation magnetization increased by 56% to 53.8 emu·g −1 , and the coercivity d...

Zusammenfassung:In the present work, FeCoNiCuTi high-entropy alloy (HEA) was heat-treated at different temperatures. After heat treatment at different temperatures, the crystal structure maintained its FCC + Laves phase structure. The saturation magnetization increased by 56% to 53.8 emu·g −1 , and the coercivity did not change. At 950 °C, the maximum strain value was 12.4%, which was approximately 4 times that of the as-cast alloy. The magnetic and mechanical properties of the FeCoNiCuTi HEA were much better after heat treatment. The FeCoNiCuTi HEA had very good thermal stability.
