研究了Ti-45Al-(5-10)Nbat.%合金经多步热处理后的组织转变。通过两步热处理，合金的组织得到了显著的细化。不连续粗化似乎在所获得的转变中起着重要作用，但不能解释观察到的所有微观结构特征，因此应考虑其他机制。
Microstructural transformation via multi-step heat treatments on a Ti–45Al–(5–10)Nbat.% alloy has been studied. A significant refinement of the microstructure of the alloy has been achieved by a two step heat treatment. Discontinuous coarsening seems to play an important role in the transformations obtained, but can not explain all the microstructural features observed, so other mechanisms should be considered.
