Recent Advancements in steel promise to reduce weight of vehicles while making them safer. Which in effect means improved gas mileage. The process also takes less energy to produce the steel.
Self-taught metallurgist creates lighter, stronger steel in a flash
Having been around for a few centuries, steel is what is known as a "mature technology" and the basic process of heat-treating has remained largely unchanged in the modern age. So when self-taught metallurgist Gary Cola approached engineers at Ohio State University claiming to have found a way to increase the strength of steel by seven percent, they were justifiably skeptical. However, after the engineers tested steel produced using the new method, Cole's claims were borne out and the engineers set about understanding what was happening.
Lolla says this unique microstructure boosts the metal's ductility, meaning it can crumple a lot more before breaking. This, coupled with the steel's ability to be thinned and lengthened without losing its strength, make it an ideal process for the automotive industry, say the researchers. Carmakers would be able to build frames that are up to 30 percent thinner and lighter without compromising safety, with the steel also acting as an impact-absorber. Alternatively, the steel could be used to reinforce an armored vehicle without weighing it down.
Cola also says his process is also environmentally friendly as it consumes less energy per kilogram of steel processed compared to traditional methods and uses water instead of oils or molten salt.
