Heavier steel products, such as plates, I beams, angel iron, pipe, and bar, form the structural frames of buildings, Bridges, ships, automobiles, roadways, and many other structures.

The majority of the structural components produced by fixed die pressing are iron-based. The powders are elemental, pre-alloyed, or partially alloyed.

This paper presents recent progress in research and development on iron aluminides as high - tech structural materials, including main situation in both fundamental research and alloy application.
