在过去的几年中，取得了相当大的进展，在获得可重复的力学性能数据的二元FeAl合金。两组观察结果是这一进展的基础。首先，在高温下存在于FeAl中的大的平衡空位浓度在冷却期间容易保留，并且这些强烈影响低温机械性能。第二，室温延展性受到水蒸气的不利影响。本文的目的是突出我们的理解的关键现象，并显示如何理解的因素控制的屈服强度和断裂行为，随后从上述两个效果的发现。
In the last few years, considerable progress been made in obtaining reproducible mechanical properties data for binary FeAl alloys. Two sets of observations are the foundation of this progress. The first is that the large equilibrium vacancy concentrations that exist in FeAl at high temperature are easily retained during cooling, and that these strongly affect the low-temperature mechanical properties. The second is that room-temperature ductility is adversely affected by water vapor. The purpose of this paper is to highlight our understanding of key phenomena and to show how an understanding of the factors which control the yield strength and fracture behavior has followed from the discovery of the above two effects.
