Description
An equal-molar CoCrFeMnNi, face-centered-cubic high-entropy alloy system and a face-centeredcubic 304L stainless steel described as a medium-entropy system, are measured by in-situ neutron-diffraction experiments subjected to continuous tension at room and several elevated temperatures, respectively. With spallation neutron, the evolution of multiple diffraction peaks are collected simultaneously for lattice-elasticity study. Temperature variation of elastic stiffness of a single face-centered-cubic-phase Ni and a single face-centered-cubic-phase Fe are compared as low-entropy metals. The CoCrFeMnNi high-entropy alloy show distinct lattice anisotropy. The data is shown on Scripta Materialia (doi:10.1016/j.scriptamat.2015.01.011). The mechanism will be reported.
