Metallurgy / Materials Evaluation
Since 1967, the engineers and scientists at Exponent (formerly Failure Analysis Associates) have studied components closely for pre-existing defects and evaluated specific properties for compliance with specifications and contributions to the causes (or potential cause) of failure. We have photographed and analyzed microstructures and corrosion features, as well as determined the operating and residual stresses and compared them to the material’s strength. We have looked at everything from giant turbines to consumer products and medical devices, using the latest in physical testing and analytical techniques in our laboratories across the country. Our experimental testing and analytical modeling specialists collaborate on the analysis of complex technical problems. This integrated effort encourages a constant cross-fertilization of productive ideas, provides a unique insight into our clients' concerns, and differentiates us from other consultants. This comprehensive approach enables us to offer high-quality, cost-effective services.
Our services include:
- Failure analysis
- Bulk and surface chemical analysis
- Corrosion science and engineering
- Defect detection and effect investigation
- Electrochemical and corrosion laboratories
- Embrittlement phenomena
- Environmental effect assessment
- Fractography
- Fabrication and material processing
- Fatigue and fracture evaluation
- Infrastructure corrosion
- Laboratory testing
- Life assessment
- Manufacturing process analysis
- Material characterization, selection, and compatibility
- Microscopy
- Joining and welding
- Non-destructive evaluation
- Polymer, composites, and elastomers
- Adhesion and coating evaluation
- Rheology and rheometry
Collectively, Exponent's metallurgists, polymer and corrosion scientists, electrochemists, and ceramists have many years of experience in the prevention and analysis of material failures. As a result of this close familiarity with all types of materials, our scientists and engineers have a unique ability to provide advice on how to avoid problems early in the design cycle, when materials are being selected.
