Boon to car industry? Scientist Invents New Way To Make Steel Strong, But Light.

How to make steel 7 percent stronger, but lighter? Detroit entrepreneur Gary Cola has an answer.

Cola invented a heat-treatment that makes steel 7 percent stronger than any steel on record and that too in less than 10 seconds.

Most steels are heat-treated at around 900 degrees Celsius for a few hours. Others are heated at similar temperatures for days. But, the latest process took less than 10 seconds.

The steel, now trademarked as Flash Bainite, has tested stronger and more shock-absorbing than the most common titanium alloys used by industry. Flash Bainite is the strongest, most ductile, lean alloyed, readily weldable, least expensive ultra strength metal known to man.

"Steel is what we would call a 'mature technology.' We'd like to think we know almost everything about it, If someone invented a way to strengthen the strongest steels even a few percent, that would be a big deal. But 7 percent? That's huge," Indian expert Prof. Suresh Babu said in a statement.

The discovery may lead to making cars and military vehicles lighter, stronger, and more fuel-efficient. If the invention is successful, carmakers could make frames that are up to 30 percent thinner and lighter without compromising safety.
