| Abstract Scope |
The present work studies compression behavior of the Al5Co35Cr35Fe20Ni5 high entropy alloy between room temperature and 800°C through in-situ diffraction experiments using synchrotron radiation. The alloy was processed through a conventional route involving vacuum induction melting, casting in a graphite mould, homogenizing at 1200°C for 2 h and subsequent forging at 1200°C. After forging, the sample was annealed at 1200°C and, then, quenched in water. A forging reduction of 50 %was achieved in one step. The microstructure of the forged alloy consists of an austenitic matrix with coarse ferritic particles located within and at grain boundaries of austenitic grains. Furthermore, the ferritic particles contain a fine dispersion of nanometric particles of the ordered B2-phase. The alloy exhibit high strength up to 500°C. In situ experiments have been an effective tool for revealing the contribution of each phase to the strength of the alloy in the studied temperature range. |
