Overview

High temperature creep experiment evaluated fracture morphology in T92 steel, suggesting influences of precipitates.

Key Points

  • Creep rupture properties were examined, revealing distinct fracture types under varying stress levels.
  • Testing showed that T92 steel exhibited plastic transgranular fracture at high stress and brittle intergranular fracture at low stress.
  • Analysis indicated that coarsening precipitates and grain boundary interactions significantly affected creep cavity formation.
  • The study underscores the role of precipitates in the development and expansion of creep fractures.
