对经过轧制热加工的金属间化合物Ｆｅ－３６．５ａｔ％Ａｌ及其加入Ｍｎ元素的合金进行室温下的拉伸试验。结果表明，未加和加入Ｍｎ的ＦｅＡｌ合金，在一定的应变速率范围内，表现出对应变的敏感性，加Ｍｎ合金具有较高的延伸率和强度，但应变速率的变化以及Ｍｎ的加入并未改变ＦｅＡｌ合金的断裂模式，均为沿晶和穿晶解理断裂的混合模式。
Tensile tests were conducted at room temperature on the hot rolled intermetallic compound Fe-36.5 at% Al and the Mn alloy added thereto. The results show that FeAl alloys without addition of Mn show a sensitivity to strain at a certain strain rate. Mn alloys have higher elongation and strength, but the strain rate changes and Mn addition The unchanged fracture mode of FeAl alloy is the mixed mode of intergranular and transgranular cleavage fracture.
