Electron Backscatter Diffraction (EBSD)

EBSD can be used to identify different carbides.

EDAX Periodic Table of Elements - Carbon

Heat resisting alloys are strengthened by a number of different precipitate phases such as carbide and intermetallic phases, and their stability at high temperatures is essential to alloy design. EBSD pattern analysis combined with EDS measurements of the approximate composition allows a highly efficient phase identification. The backscattered electron image is of an Fe-26Al-5Cr-1.5Mo-1.0C (at%) alloy. Three kinds of carbide phases were identified, M6C (bright & coarse), M7C3 (grey & needle shaped) and M2C (bright & fine). M identifies a phase-dependent mix of Cr, Mo and Fe.

EBSD is an ideal tool for measuring grain size, orientations and plastic strain in polycrystalline diamond.

Energy Dispersive Spectroscopy (EDS)

Silicon Carbide
A SiC sample with a thin Carbon ribbon-like structure layered into the matrix. This C layer can be very difficult to measure, both due to its extreme thinness and the difficulty in generating and collecting the low energy C X-rays. However, when analyzed under ideal conditions, TEAM™ EDS with Octane SDDs can clearly resolve sub-50 nm thickness.
