Abstract:Mechanically strong and ductile load–carrying materials are needed in all sectors, from transportation to lightweight design to safe infrastructure. Yet, a grand challenge is to unify both features in one material. We show that a plain medium-manganese steel can be processed to have a tensile strength >2.2 gigapascals at a uniform elongation >20%. This requires a combination of multiple transversal forging, cryogenic treatment, and tempering steps. A hierarchical microstructure that consists of laminated and twofold topologically aligned martensite with finely dispersed retained austenite simultaneously activates multiple micromechanisms to strengthen and ductilize the material. The dislocation slip in the well-organized martensite and the gradual deformation-stimulated phase transformation synergistically produce the high ductility. Our nanostructure design strategy produces 2 gigapascal–strength and yet ductile steels that have attractive composition and the potential to be produced at large industrial scales.

寄生虫在昆虫肚子里"扎根",靠的是一个保守蛋白家族
一种寄生虫只有头发丝的几分之一粗,却能牢牢黏在昆虫的胃瓣膜上,像钉子钉进木板一样稳,它可不是随便黏黏,这个黏附动作关系到能不能传染给人。这就是利什曼原虫,一种通过白蛉叮咬传播的寄生虫,引起利什曼病,全球有超过10亿人面临感染风险。
