Description
Advanced Electron Backscatter Diffraction service for crystallographic orientation, grain structure, and phase mapping of materials at the microscale. EBSD enables quantitative correlation between microstructure, texture, and material performance, particularly in polycrystalline and engineered materials.
Key Applications
-
Grain size and grain boundary analysis
-
Crystallographic orientation and texture mapping
-
Phase identification and phase distribution
-
Deformation, recrystallization, and failure analysis
-
Process optimization and quality assessment

Sample Preparation Support
-
EBSD-specific mechanical and vibratory polishing
-
Damage and deformation layer removal
-
Conductive coating guidance (if required)
-
Surface quality validation prior to mapping
-
(EBSD data quality is critically dependent on surface preparation and strain-free conditions.)

Important Note
EBSD is sensitive to surface damage and crystallinity.
Amorphous materials or poorly prepared surfaces may not yield indexable patterns and may require complementary techniques such as TEM or XRD.
