A constitutive model based on the dislocation glide and deformation twinning is adapted to face-centered cubic high-entropy alloys (HEAs) as exemplified by the CrMnFeCoNi system. In this model. the total dislocation density is considered as the only internal variable. while the evolution equation describing its variation during plastic deformation is governed by the volume fraction of... https://www.markbroyard.com/deal-time-gtech-airram-mk2-k9-roller-roll-brush-bar-filter-vacuum-cleaner-hot-on-sale-best-find/
