摘要
近年来,金属间化合物 Fe_3Al 合金由于具有高强度、耐腐蚀、低密度和低成本等一系列优点而受到世界各国材料科学工作者的普遍重视,开展了大量的研究工作,获得了许多基本数据,取得了很多有规律的结果。本文对国外在 Fe_3Al 方面发表的大量文献和作者近两年开展的工作进行综合评述,主要内容包括相结构和晶体缺陷;物理和力学性能;合金脆性以及组织结构和力学性能等方面。
In recent years,much attention has been paid extensively to intermetallics Fe_3Albecause of its high strength,excellent oxidation and sulfidation resistance,lower density and lowmaterial cost.Many research works have been finished and many valubale results have beenachieved.In this review,we summarize a large amount of literatures published and our workconcerning Fe_3Al.This report will concentrate on phase structure and crystal defects,physicaland chemical properties,brittleness nature,microstructure and mechanical properties.
