Electron Back-scatter Diffraction-EBSD

EBSD – Electron Backscatter Diffraction

Commonly, variations in the microstructure of materials can have as much or more of an impact on the properties of interest than the chemistry of the bulk sample, even though chemical analysis to determine the gross composition of a sample is frequently very useful in materials science and other related applications. Infinita Labs uses the potent technique of electron backscatter diffraction to examine solid sample crystalline phases down to sub-micron levels of detail. The faint, destructive interference bands produced in backscattered electrons in a particular geometry are seen using the intrinsic wave properties of an electron beam. The images of these interference patterns can be utilised to determine crystal orientation on a sub-micron scale in addition to crystal geometry. This enables the mapping and analysis of grain size, orientation, association, and deformation (among other aspects), in two- or three-dimensional data sets. To get previously unattainable insight into the properties of materials, this data is frequently immediately interfaced with property modeling and simulation research.

Strength, magnetic characteristics, and hardness can frequently be significantly impacted by the orientation and association of grains in alloys and metal parts. With varying grain sizes, sintering effects, and levels of crystallinity, ceramics are diverse and can have drastically different properties, including piezoelectric or magnetically active ceramic compounds. Even petrographic analyses, crystalline polymers, and composites all profit from knowing more about the micro-scale crystalline characteristics of the bulk material. With the addition of EBSD to its full complement of crystallographic tools, Infinita Labs is ready to help its clients with cutting-edge analysis for their complex materials analysis needs. This helps to clarify and draw attention to key features.
