Performing materials/ metallurgical consulting – including testing, analysis and solutions to ensure structural integrity, and compliance to codes including ASTM, NACE, AWS, API and ASME.
Materials and metallurgical testing quantifies the properties of metals and is often used to determine whether it conforms to a required specification.
The primary benefits are (1) Ensuring the right materials/ properties for your application, or (2) In conjunction with corrosion and chemical testing – determining the cause of equipment failure.

Metallurgical Failure Analysis
Visual and scanning electron microscopy techniques are used to determine metallurgical failures due to manufacturing process problems, defects, contamination and corrosion.
Often, equipment design life is often compromised through inadequate manufacturing processes such as welding, thermal/ transient conditions, and high temperature conditions. At elevated temperatures, creep and component strains occur, especially in welded and bolted joint connections. Defects often occur in welded, cast and forged parts. Parts with complex geometries often include crack starters, such as metallurgical notch effects – and thus testing is required. Read about the various types of Nondestructive Testing (NDT).
Other metallurgical failures may result from vibration, thermal fatigue, thermal ratcheting, creep, fatigue, and fracture. We have 30+ years experience in engineering design, analysis, and materials science – determining modes of failure, crack initiation sites, probable rates of propagation, and fatigue life due to complex sources of dynamic loading.

Our experts come from diverse backgrounds, including power generation, materials & fabrication, fatigue/ failure analysis, and finite element analysis (FEA). FEA is often used along with materials/metallurgical testing and analysis to identify failure modes.
Interdisciplinary teams are essential for performing most failure analyses, since the root cause is rarely the result of a single variable. Understanding not only the metallurgical properties but also the environmental effects and stresses to a system or component is important in determining the cause of a material failure.
Once we identify component failure modes, we perform design modifications to ensure structural integrity and compliance to relevant codes.
Our licensed Professional Engineers and Certified Welding Inspectors provide clients with support across the spectrum of welding and joining challenges – including code compliance, weld and joint inspection, and mechanical testing.
