Abstract Scope |
The in-situ neutron diffraction was conducted to investigate the deformation behavior of the Al0.3CoCrFeNi high-entropy alloy (HEA) with a face-centered-cubic (FCC) phase at ambient temperature. The wall spacing and density of dislocation are calculated based on the diffraction data, which are related to cyclic hardening. The lattice strain evolution, based on selected loading cycles, was plotted to demonstrate the deformation mechanism during cyclic loading. It will facilitate a better understanding on the mechanical behavior of high-entropy alloys with FCC crystal structures. |
