Nano-engineered steels: properties and application

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.
