Web20 nov. 2024 · Anneal hardening phenomenon has been observed in dilute Al-doped al x cocrfemnni (x = 0, 0.1) high-entropy alloys, where peak hardness is reached at an annealing temperature of 500 °C (recrystallization temperature).. Dislocation substructure strengthening is identified to explain the observed annealing hardening phenomenon. Web1. Use single crystals and anneal out all the dislocations (expensive - especially with large items like turbine blades, and impossible with very large items like airplane wings or bridges). 2. Work hardening of the metal - this moves all dislocations to grain boundaries (the dislocation essentially becomes part of the grain boundary).
