In Situ MMC Properties

Courtesy of LSM

• Increased modulus

  • LM24: E=70 GPa
  • LM24 + 7% TiB2: E=80 GPa

• Higher hardness

  • 2024: Hv=160
  • 2024 + 5% TiB2: Hv=175
  • 2024 + 10% TiB2: Hv=190

• Improved wear properties

  • Higher transition load: mild to severe wear
  • Lower coefficient of friction
  • Less counterface wear than coarser SiC-reinforced MMCs
