摘要: The hot deformation behavior of as-cast and homogenized Al0.5CoCrFeNi high entropy alloys (HEAs) during isothermal compression was investigated as a function temperature strain rate. Results indicated that flow stress in state always higher than an under the same conditions. Moreover, optimum thermo-mechanical processing (TMP) conditions for working were identified 945–965 °C 10−1.7–10−1.1 s−1 easier to determine practice. Constitutive equations, both states, correlating with rate also determined.
