Procedure to conduct a Failure Analysis
Cause of failure is determined using state-of-the-art analytical and mechanical procedures and often includes simulated service testing. A combination of analysis and physical testing locates problems and provides recommendations for solutions.
A complete evaluation sequence of the failure investigation steps are summarized as under:
- Collection of background data and selection of samples
- Preliminary examination of the failed part
- Complete metallurgical analysis of failed material
- A thorough examination of the failed part including Macroscopic and Microscopic examination and analysis using electron microscopy
- Tests including Weld Examination, Case Depth, Decarburization Measurement, Coating/Plating Evaluation, Surface Evaluation and/ or Grain Size Determination
- Chemical analysis (bulk, local, surface corrosion products, deposits or coating and microprobe analysis)
- Tests to simulate environmental and physical stress that may have played a role in the failure
- Selection and testing of alternative products and/or procedures that will significantly improve performance
- Analysis of fracture mechanics.
- On-site evaluation and consulting services
- Analysis of all the evidence. Formulation of conclusions and writing the report (Including recommendations).
