FeAl金属间化合物研究现状

Research Status of FeAl Intermetallics Compound

FeAl金属间化合物是一种新型的高温材料,在最近的研究中受到极大的重视,由于其具有长程有序的特殊结构,从而带来一系列优异的特性,如优异的高温抗氧化和抗硫化性、相对较低的密度和低廉的价格等。但室温脆性是FeAl金属间化合物的一个显著弱点。对FeAl金属间化合物近年来的研究现状包括FeAl金属间化合物的抗氧化、抗硫化性和室温脆性等进行了较为详尽的综述。

Iron aluminides based on Fe3Al and FeAl are of interest for structural applications at elevated temper atures in hostile environments. This is because they generally possess excellent oxidation and sulfuration resistance, relatively low density , and low material cost. Considerable effort has been devoted to understanding the brittleness of FeAl intermetallics. This paper reviews the study on FeAl interrnetallics, including brittleness, oxidation and sulfuration resistance behavior.
