Failure Analysis

Failure analysis services provide answers to the questions “How?” and “Why?” when a critical component fails. Understanding engineered materials lends greater insight into the root cause of unexpected mechanical, thermal, and corrosion damage. Our laboratory is equipped with a wide variety of metallurgical and photographic instruments used to conduct failure analysis investigations. Investigations are conducted by an experienced and highly skilled staff of metallurgists trained in such disciplines as:

Microstructural Characterization of Metals

DNFM’s metallographic microscope is designed to document microstructure images at 63x, 125x, 247x, and 500x magnifications. Metallographic preparation and examination can reveal important features at the fracture face that may have gone unnoticed from different perspectives. Inspecting a cross section of the fracture face for plastic deformation, secondary cracking, and evidence of corrosion is essential to a failure analysis investigation.
