Testing items
Macroscopic fracture analysis: observation of fracture morphology, localization of fracture source, examination of fracture path and deformation characteristics, preliminary determination of fracture mode.
Microscopic fracture analysis: Scanning electron microscopy and metallographic microscopy observation to identify features such as ductile dimples, cleavage, fatigue striations, intergranular fracture, and creep voids.
Material performance review: chemical composition, hardness, metallographic structure, tensile, impact, creep and other mechanical property testing and verification.
Fracture property determination: distinguish between ductile fracture, brittle fracture, fatigue fracture, high-temperature creep fracture, stress corrosion cracking, hydrogen embrittlement fracture, corrosion fatigue fracture, etc.
Analysis of working conditions and stress: comprehensively analyze the causes based on the stress state, usage environment, assembly process, heat treatment, and welding quality.
Comprehensive determination and improvement of failure causes, recommendations for protection and material selection optimization.
