Why Failure Analysis?
Any engineering material can fail in any number of ways, including inadequate design allowances, improper manufacturing techniques, or service conditions that exceed design margins. Failures are generally costly, not only in terms of repair, but also in terms of downtime and the increased engineering support required to prevent future failures.
However, once a part has failed, it makes sense to carry out a thorough investigation to understand the root cause and to develop strategies that prevent a recurrence. A well thought out, systematic and carefully executed failure analysis at Subodh provides the Knowledge required to help prevent future problems.
The visual examination of failed components can often quickly answer questions such as:
- What was the mode of failure?
- Did it crack, or was there a uniform or pitting corrosion failure?
- Did the protective oxide film break down?
- Were the welds visibly contaminated
Typical Metallurgical Failure Mechanisms
- Fatigue Failures
- Corrosion Failures
- Stress Corrosion Cracking
- Ductile and Brittle Fractures
- Hydrogen Embrittlement
- Liquid metal Embrittlement
- Creep and Stress Rupture
We follow a step by step systematic approach to
failure analysis of metals.
