由于铁铝化合物对高温氧化和硫化具有高的抗力,故有希望作为300和400系列不锈钢及某些镍基合金的廉价替代物用作结构材料。但由于它们受到室温延性差的限制,为了使成品具有最佳性能,不得不采用精心的加工方法。采用标准的锭铸冶金工艺与初始铸态组织等因素有决定性的关系,同时室温下合金锭组织延性差又排除了进行冷加工的可能性。为此,英国最近有人进行了一项初步试验,先将熔融合金铸成带材,然后再进
Because of their high resistance to high temperature oxidation and sulfidation, ferric aluminum compounds are promising as a structural material as an inexpensive alternative to 300 and 400 series stainless steels and some nickel-based alloys. However, due to their poor ductility at room temperature, elaborate processing methods have to be employed in order to achieve the best performance of the finished product. The use of standard ingot casting metallurgical process and the initial cast microstructure and other factors have a decisive relationship, while room temperature alloy ingot poor ductility ruled out the possibility of cold. To this end, the United Kingdom recently conducted a preliminary test, the first molten alloy cast strip, and then re-enter
