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, due to a series of advantages such as high strength, corrosion resistance, low density and low cost, intermetallic Fe_3Al alloy has been widely valued by material scientists all over the world. A great deal of research work has been carried out and many basic data have been obtained. Has made a lot of regular results. In this paper, a large number of foreign literature published in Fe_3Al and the author carried out a comprehensive review of the work carried out in recent years, the main contents include phase structure and crystal defects; physical and mechanical properties; alloy brittleness and organizational structure and mechanical properties and so on.
