Problem addressed

The invention solved the strength-dictulity trade-off problem and brings about an advanced steel that is strong, highly tensile and hight ductile.

Key impact
  • High strength and ductility, overcome the "strength-ductility" trade-off problem
  • Low raw materials cost, ~20% of the maraging steel
  • Light weight
  • Simple fabrication process and high manufacturing scalability
Application
  • Advanced high stength and light weight steel for the automative industry
  • Advanced high stength and light weight steel for the aerospace industry
  • Advanced high strength steel for construction industry like the galvanized steel wires used by suspension bridges
