Nanocrystalline CoCrNi equiatomic alloy processed by high-pressure torsion shows annealing induced hardening at 500 °C and 600 °C. The microstructural characterization indicates the hardening phenomenon is not because of precipitation hardening. The annealing-induced hardening is explained based on the reduced dislocation density and grain boundaries relaxation.

高压扭转加工的CoCrNi中熵合金的退火诱导淬火

通过高压扭转处理的纳米晶CoCrNi等原子合金在500°C和600°C时表现出退火诱导的硬化。显微组织表征表明硬化现象不是由于沉淀硬化。基于降低的位错密度和晶界弛豫来解释退火引起的硬化。
