对 Pilgered 两相 Zr-2.5 Nb 进行恢复（400°C）和再结晶（700°C）退火——主要目标是实现相关的微观结构发展。回复和再结晶的影响用硬度、晶格应变、冷加工储存能和残余应力的变化来表示。尽管恢复并没有引起晶粒/相结构的显着变化；第二相的可见粗化与再结晶有关。即使在初次再结晶完成后，这种粗化仍在继续，同时显微结构和晶体结构发生显着变化。
Pilgered two-phase Zr-2.5 Nb was subjected to recovery (400°C) and recrystallization (700°C) annealing – broad objective was to bring out associated microstructural developments. Effects of recovery and recrystallization were indexed in terms of changes in hardness, lattice strain, stored energy of cold work and residual stress. Though recovery did not cause significant changes in grain/phase structure; visible coarsening of 2nd phase was associated with recrystallization. Such coarsening continued even after the completion of primary recrystallization, with concurrent and noticeable changes in microstructure and in crystallographic texture.
