(1)耐热铁基合金 日本FuJi Oozx和Tohoku钢铁公司开发了一种性能和成本介于用于汽车发动机排气阀材料的镍基合金和21Fe-4N铁基合金之间。据研究人员在1998年SAE国际会议暨博览会上发表的论文,他们旨在设计一种在高温条件下具有良好疲劳强度的铁基合金。该合金的最终成分的选择为Fe-23Cr
(1) Heat Resistant Iron Based Fuels Japan’s FuJi Oozx and Tohoku Steel developed a performance and cost range between nickel-base alloys and 21Fe-4N iron-based alloys for automotive engine exhaust valve materials. According to researchers at the SAE International Conference and Exposition 1998, they aimed to design an iron-based alloy with good fatigue strength at high temperatures. The final composition of the alloy was chosen as Fe-23Cr
