由于铬提供了钢的抗腐蚀性能,在世界上95.1%的铬蕴藏在南非和津巴布韦这两个国家。因此,铬成为极稀缺的元素。近来发表的文章,极力主张研究用Fe-Mn-Al-C合金代替奥氏体Fe-Ni-Cr合金。本文报导在500℃和T00℃下显示出良好抗氧化性能的几种Fe-Mn-Al-Si-C-X合金的结构、显微组织和氧化特性。合金设计的目标是得到在奥氏体中保持尽可能多铝的Fe-Mn-Al合金。设想铝将扩散到合金的表面,
As chromium provides the corrosion resistance of steel, 95.1% of the world’s chromium is in the world in South Africa and Zimbabwe. As a result, chromium becomes an extremely scarce element. Recently published articles, strongly advocated the use of Fe-Mn-Al-C alloy instead of austenitic Fe-Ni-Cr alloy. This paper reports the structure, microstructure and oxidation properties of several Fe-Mn-Al-Si-C-X alloys that exhibit good oxidation resistance at 500 ° C and T00 ° C. The goal of the alloy design is to obtain Fe-Mn-Al alloys that retain as much aluminum in austenite as possible. Imagine aluminum will diffuse to the surface of the alloy,
