چکیده انگلیسی
The equiatomic CoCrFeMnNi high entropy alloy prepared by powder metallurgy has homogenous chemical composition and microstructure. The mechanical properties of the CoCrFeMnNi high entropy alloy at the strain rates (1â¯Ã 10â4 sâ1 to 0.1â¯sâ1 and 1â¯Ã 103 sâ1 to 3â¯Ã 103 sâ1) and the temperature (298â¯K, 673â¯K and 1073â¯K) were investigated. Results indicate that the yield strength of the CoCrFeMnNi high entropy alloy is in the range of 350-700â¯MPa, increasing sensitively with increasing the strain rates, especially at a high strain rate (larger than 1â¯Ã 103 sâ1). The serration behavior of the high entropy alloy is observed on the flow stress curves of the alloy deformed at a low strain rate of 1â¯Ãâ¯10â3 sâ1 and the high strain rates (1â¯Ã 103 sâ1 to 3â¯Ã 103 sâ1). Influences of the strain rate and the temperature on the serration behavior of the CoCrFeMnNi high entropy alloy are discussed.
