Abstract
Steel has a dominant position among other engineering materials
due to its abundance and the easiness of achieving a variety of pro perties with
different treatments, low cost, and recycling possibilities. Today’s modern en
gineering tends to develop new innovative materials that will have superior
properties at a reasonable cost when compared to conventional steel. The de
velopment of advanced characterization methods on a small measuring scale
and computational material design has increased the possibilities and interest
in implementing nanotechnology in steel. Steel’s microstructure can be mani
pulated at the nanometer scale, resulting in significant advancement in proper
ties. Nevertheless, there are still many challenges to overcome, such as man
ufacturing large components of bulk nanocrystalline steel, and nanostructured
steels have high strength and low ductility, making them difficult for certain
applications and thus commercialization. This paper provides a review of the
new emerging nanoengineered steels, with discussions on properties and po
tential applications. The era of nanoengineered steel has only recently begun,
and its adoption is expected to accelerate in the coming years as new research
findings demonstrate significant benefits.
