Fractography Analysis Using 3D Profilometry

Fractography is the study of features examined on fracture surfaces and has historically been investigated via Microscope or SEM. Microscope being used for macro scale analysis and SEM particularly when it is the nano or microstructure that is vital to the analysis. Both ultimately allowing for the identification of the fracture mechanism type. Although effective, the Microscope clearly has its limitations and the SEM in most cases, other than atomic level analysis, is unpractical for fracture surface measurement and lacks broad use. With advances in optical measurement technology, the 3D Non Contact Profilometer is now the instrument of choice, providing nano through macro scale 2d & 3D surface measurement.http://www.nanovea.com/Application%20Notes/fractography3dmetrology.pdf
