研究了Zr-4合金低温轧制后的显微组织和力学性能的变化，以了解该合金在低温下强度的来源。位错密度，晶粒尺寸和屈服应力的轧制产品的相关性表明，位错密度的增加，由于动态恢复的抑制是强化的主要来源。
The evolution of microstructure and the mechanical properties of cryo-rolled Zircaloy-4 were both investigated to understand the origin of the alloy’s strength processed at a cryogenic temperature. The correlation of dislocation density, grain size and yield stress of the rolled product indicated that an increase in dislocation density due to the suppression of dynamic recovery is the primary source of strengthening.
