High-strength material advancements at Wayne State University may lead to new, life-saving steel (vehicle, light)

“Our steel has twice the yield strength, has a very high tensile strength, and is close to three times the fracture toughness over advanced steels currently on the market,” said Putatunda. “In addition, it has improved strength for fatigue and impact, improved durability, lower weight, and the austempering process reduces energy consumption and eliminates the post-treatment process.”

“The steel has been found to have the strength and durability necessary for armored vehicles to resist improvised explosive devices because of its extremely high fracture toughness,” said Putatunda. “Our steel could potentially save human lives against explosive attacks.”

I guess these different metals are mostly for different purposes.
