You'd be forgiven for dismissing an amateur metallurgist if he claimed to have improved upon the presumably perfected technology of steel making. But Flash Bainite, the creation of Detroit entrepreneur Gary Cola, wowed a team of Ohio State University engineers by turning centuries of alloy processing on its head. Instead of heating the metal for hours or days, this well-equipped DIYer boosted the temperature -- quickly baking, then cooling sheets of steel that are 7-percent stronger than other forms and tougher than some titanium alloys. Flash Bainite is also more ductile than other steels, allowing it to crumple more before breaking -- perfect for absorbing impacts. Obviously this means
