摘要：
It is established that the critical shear stresses under tensile strain of Al0.3CoCrFeNi high-entropy alloy single crystals are independent of crystal orientation. It is shown that the development of the planar dislocation structure in Al0.3CoCrFeNi single crystals at T = 296 K leads to a decrease in the ratio between the strain-hardening coefficient and shear modulus relative to that the value for Cu single crystals, where the cellular dislocation structure is developed at the similar staking fault energy.
