Researchers Make Super-Strong Steel That's Also Tough
05/14/2020 - Researchers at the University of Hong Kong and the Lawrence Berkeley National Laboratory have developed a way to raise the strength-to-toughness ratio in ultrahigh-strength steels, a development that has applications in structural materials.
“In this latest breakthrough, we attained an unprecedented strength-toughness combination which can address a major challenge in safety-critical industrial applications — to attain an ultrahigh fracture toughness so as to prevent catastrophic premature fracture of structural materials,” said professor Huang Mingxin, who runs the University of Hong Kong’s advanced alloys laboratory.
“The breakthrough also changes the conventional view that attaining high strength will be at the expense of deteriorating toughness, which invariably leads to the embrittlement of structural materials and greatly limits their application," he said.
The team’s work appears in the journal Science. You can also read more in Popular Mechanics.
