NEXT GENERATION DRX REQUIREMENTS

• Broad range of requirements for DRX with improved properties

  • affordability drives most applications
  • an increase in fracture toughness (from ~20 to ~30 MPA¦m) is a trigger point for critical components
  • a moderate increase in temperature capability over Al alloys (to 150–250°C) will allow substitution for Ti
  • highly-loaded structures require DRX with improved strength (DRTi)
