以FeAl为基的铁铝化合物具有诱人的高湿性能,例如低的密度,优良的抗氧化和抗硫化性以及700℃高温下的高强度,高蠕变强度。有趣的是FeAl扩大的相范围会导致产生非化学计量的铁铝化合物,并且原子种类的缺少提供了非化学计量铝化物中结构空位的形成。同时空位的浓度随着Al含量的增加而增加。一些学者曾研究过B对FeAl合金室温机械性能的影响,发现少量
FeAl-based iron-aluminum compounds have attractive high-humidity properties such as low density, excellent oxidation and sulfidation resistance, and high strength and high creep strength at a high temperature of 700 ° C. Interestingly, the extended phase range of FeAl results in the production of non-stoichiometric Fe-Al compounds, and the absence of atomic species provides for the formation of structural vacancies in non-stoichiometric aluminides. At the same time, the vacancy concentration increases with the increase of Al content. Some scholars have studied B on the mechanical properties of FeAl alloy at room temperature and found a small amount
