Dynamic response of equiatomic and non-equiatomic CrMnFeCoNi high-entropy alloys under plate impact
Source abstract
Abstract
A typical Fe-rich non-equiatomic CrMnFeCoNi high-entropy alloy (HEA), Cr 10Mn 10Fe 60Co 10Ni 10, and the equiatomic Cr 20Mn 20Fe 20Co 20Ni 20 HEA, are investigated via plate impact experiments along with in situ free surface velocity measurements. Both the initial and postmortem samples are characterized with transmission electron microscopy and electron backscatter diffraction. These two HEAs contain a single face-centered cubic phase, are texture-free, and have similar grain sizes. Dynamic yield stress and spall strength of the non-equiatomic CrMnFeCoNi are lower by ∼55 % and 15 % than those of its equiatomic counterpart, respectively. After shock compression, dislocation slips, stacking faults, Lomer-Cottrell locks and nanotwins are found in the postmortem samples of both HEAs. Due to the reduced stacking fault energy in the non-equiatomic HEA, more deformation twins and newly formed hexagonal close-packed phases are found. For spallation, intergranular voids are larger in size but smaller in quantity than intragranular voids for both HEAs. Both intragranular or intergranular voids show strong dependence on grain boundary misorientation.
