Metallurgical Analysis Detecting Defects: Find Them Before They Become a Problem
Metallurgical examinations look for internal and surface defects on test specimens, which we prepare and analyze at LTI. Our capabilities include photomicrographic examination with optical magnification from 7X to 1000X. Microstructural and macrostructural analyses are performed by our engineers on samples using a variety of metallurgical testing methods:
- Micro Examination
- Microhardness
- Inclusion/Cleanliness Rating (ASTM E-45)
- Alpha Case
- Corrosion Practice A (ASTM A-262)
- Case Depth
- Surface Finish
- Delta Ferrite (ASTM E-562)
- Eutectic Melting
- Accelerated Intergranular Attack
- Grain Size/Grain Flow
- Plating/Coating Thickness
- Decarburization/Carburization
- Microstructural Features
- Macroetch (ASTM E-381)
- High-Temperature Oxidation
- Surface Contamination & Condition
- Recast Layer Determinations
- Serial Sectioning
- Digital Imaging
- Failure Analysis & Consulting
- Metallurgical Mounting & Polishing
Additional capabilities include:
- Weld qualifications in accordance with MIL specifications, ASME codes, EN standards and the Pressure Equipment Directive
- Scanning electron microscopy (SEM)
- Energy dispersive X-ray analysis (EDS)
- Residual stress measurements by X-ray diffraction (XRD)
- Plating thickness by X-ray fluorescence spectroscopy
