Conducting the Failure Analysis

Non-Fracture Failures

  • Ductile Deformation
  • Creep
  • Distortion
  • Wear
  • General Corrosion
  • Leakage, e.g., Selective Leaching, Pitting, Crevice Corrosion

Causes of Failure

  • Poor Design
  • Imperfections in Materials
  • Imperfections in Manufacture/Fabrication
  • Overloading/Service Abuse
  • Improper Maintenance or Repair
  • Environmental Effects
  • Combinations of the above

Examination Steps

  • Assemble Background Information
  • Visual Examination of Failure
  • Fractographic Examination
  • Verify Materials Used
  • Determine Mechanical Properties
  • Metallographic Examination (Macro/Micro)
  • Analyze Corrosion Deposits
