Abstract

See full text

A steel manufacturing process can include forming an iron oxide layer on a hot band during hot rolling; reducing the iron oxide layer on the hot band to form a sponge iron layer that includes pores; the sponge-iron layer having a thickness in a range of about 0.05 μm to about 1000 μm, about 0.1 μm to about 100 μm, or about 5 μm to about 25 μm; and depositing an alloying element into the pores of the sponge iron layer to form an impregnated sponge-iron layer. The process can further include annealing the impregnated sponge-iron layer to produce an iron alloy layer carried by the substrate.
