The properties of steel can be improved in terms of fatigue, weldability, hardness, wear and corrosion resistance, ductility, and tensile strength by either alloy addition or heat treatment processes.

The surface properties of some steel alloys can be adjusted through the introduction of specific elements via diffusion. An example of such a process is nitriding, where nitrogen is diffused into the ...

Nanostructured steels are on the horizon. Transmission electron microscope micrograph showing the changes in the microstructure of nanosteel alloys with varying crystallization conditions. (Left) 500C ...

To ensure that steel delivers what it promises, its microstructure is analyzed in detail to detect weak points during early stages. Today, this is largely done via visual inspection. Component ...
