HKU Super Steel project attains major breakthrough with collaborators at Berkeley Lab in producing high strength steel at unprecedented levels of fracture resistance

 

The Super Steel project led by Professor Huang Mingxin at the Department of Mechanical Engineering of the University of Hong Kong (HKU), with collaborators at the Lawrence Berkeley National Lab (LBNL), has made important breakthrough in its new super D&P steel (produced using a new deformed and partitioned method) to greatly enhance its fracture resistance while maintaining super strong in strength for advanced industrial applications.

The findings were published in Science on 8 May 2020 in the paper titled “Making Ultrastrong Steel Tough by Grain-Boundary Delamination”
