“D&P” Super Steel: a Super-Strong and Ductile Multi-phase Steel

“D&P” Super Steel: a Super-Strong and Ductile Multi-phase Steel
Advanced Materials

Key Problem and Market Opportunity

  • Steel is the most widely used metallic materials which can be produced efficiently than any other metallic materials
  • Automotive, aerospace and defense applications require steel with ultra-high strength
  • However, increasing strength often leads to the decrease in ductility, which is known as the strength-ductility trade-off
  • Developing a strong, high tensile and yet highly ductile steel has long been the quest for many researchers
  • The world’s AHSS market is estimated to worth US$28 billion in 2017
