Metallurgical Investigation & Analysis

Corrosion Clinic has access to a wide range of analytical facilities and our experienced expert metallurgist has the expertise in metallurgical investigations and metallurgical analysis.

• Chemical composition analysis and verification of conformity to specifications, designated grades, and relevant industry standards

• Microstructure analysis and its effect on property

• Effect of hot-working and cold-working on corrosion resistance. For example, the effect of welding or overheating on the corrosion resistance.

• Effect of shot-peening and sandblasting on the resistance to pitting, crevice, and stress corrosion cracking

• Hardness of materials and its effect on susceptibility to cracking (HIC, SOHIC, SCC, SSC)

• Precipitation of intermetallics (sigma phase, chi phase, Laves phase) and compounds (carbides, nitrides)

• Alpha prime, delta prime and 475^oC embrittlement

• Weld metallurgy, weldment corrosion, weld decay, and knife-line attack

• Brazing and Soldering processes and their effect on corrosion resistance of alloys

• Cast and wrought steels and alloys: comparable national and international grades and their corrosion resistance

• Interpretation of standards pertaining to chemical compositions & mechanical properties for metals and alloys

• Verification of the degree of surface preparation in steel structures subjected to sandblasting and painting

Our expertise in metallurgical investigations and metallurgical analysis has enabled us to act as expert metallurgist in litigation and arbitration cases related to corrosion, materials, metallurgy, paints & metallic coatings. With internationally recognized professional certification and professional registration, we can help you win your case not only in local courts but also in courts of other countries.
