A review on the current status of Fe–Al based ferritic lightweight ...
网页2023年8月1日 · Fe–Al based lightweight steel have good oxidation resistance due to the formation of thin adherent alumina layer similar to the formation of chromium layer in case of ferritic stainless steel. Fe–Al based alloys with higher Al content (above 12 wt%) have displayed excellent oxidation resistance up to moderate temperature of 600 °C.
The Al-Rich Part of the Fe-Al Phase Diagram - Springer

A series of 19 alloys was produced and heat-treated at temperatures in the range from 600 to 1100 °C for up to 5000 h.
Mechanical properties and electronic structures of Fe-Al …
网页2017年2月1日 · Fe-Al system, including Fe 3 Al, FeAl, FeAl 2, Fe 2 Al 5, FeAl 3, has a huge potential in industrial applications. For example, high temperature structural materials, composite materials, protective coating for materials and function materials.
Achieving room-temperature brittle-to-ductile transition in
网页2020年9月23日 · The challenge in developing Fe-Al compositions that are both lightweight and ductile lies in the intrinsic tradeoff between Al concentration and brittle-to-ductile transition temperature. Here, we show that a room-temperature, ductile-like response can be attained in a FeAl/FeAl 2 layered composite.
Fe–Al–Mn–C lightweight structural alloys: a review on the ...
网页2013年3月12日 · Fe–Al base ferritic low-density alloys can contain medium Mn of 6–8% . This type of alloy can have either disordered A2 α-(Fe, Al), B2-ordered FeAl or DO3-ordered Fe 3 Al as the dominant phase. They have considerable potential as structural materials for high-temperature applications.
