Strong steel is important for infrastructure such as the Golden Gate Bridge.


Steel is an important engineering material with properties that change with different processing techniques. Djaziri et al. found a new route for strengthening steel by using severe mechanical deformation. The improved strength comes from regions of Fe-C martensite, a known strengthening phase that normally requires quenching from high temperature. Extremely quick drawing of steel wires seems to have a similar effect without requiring high-temperature processing.
