从Ｆｅ－（８～４０）Ｎｉ－（１０～３０）Ｃｒ－（３～８）Ａｌ合金中筛选出３种γ相合主，它们的抗氧化性与ＦｅＣｒＡｌ合金相同，热强性、抗脆化能力和塑性与Ｃｒ_(２０Ｎｉ_(８０)合金相当，而且有良好的铸造、冷加工和焊接性能，合金生力成本只有Ｃｒ_(２０)Ｎｉ_(８０)的１／３，在耐热和电热领域有重要的应用前景。选出了２种γ＋α双相合主，与ＦｅＣｒＡｌ合金相比，其抗氧化性相同，热强性和抗脆化能力略高，塑性稍低，可用于高使用温度耐热结构元件。α相合金塑性很低，但可从它极高的强度和硬度特性开发实际应用。添加稀土元素对发展新合金起关键作用．
Three kinds of γ phase co-hosts were screened from Fe- (8-40) Ni- (10-30) Cr- (3-8) Al alloys. Their oxidation resistance was the same as that of FeCrAl alloy, Its ability and ductility are comparable with that of Cr 20Ni 80 alloy, and it has good casting, cold working and welding properties. The raw material cost is only 1/3 of that of Cr 20 Ni 80, which is important in the field of heat and electric heating Of the application prospects of the selected two kinds of γ + α biphasic master, compared with FeCrAl alloy, the same oxidation resistance, thermal strength and embrittlement slightly higher plasticity slightly lower, can be used for high temperature heat-resistant structural components The alphaphase alloy is low in plasticity but can be developed for practical applications from its very high strength and hardness properties.Adding rare earth elements is a key contributor to the development of new alloys.
