序言本文旨在鼓励科研人员和合金设计师去探索发展一种新的奥氏体不锈合金系的可能性,这种合金系将以锰和铝代替重要而昂贵的合金元素镍和铬。这种新型不锈钢将因加入铝而得到它的抗氧化性和抗腐蚀性。众所周知,Fe-Al合金具有极好的抗氧化性,但因为它们是铁素体组织,所以很脆,而且高温强度差[1—3]。 Preamble The purpose of this article is to encourage researchers and alloy designers to explore the possibility of developing a new family of austenitic stainless steels that will replace the important and expensive alloying elements of nickel and chromium with manganese and aluminum. This new stainless steel will have its oxidation and corrosion resistance due to the addition of aluminum. As we all know, Fe-Al alloys have excellent oxidation resistance, but because they are ferrite, it is very brittle, and the high temperature strength difference [1-3].
