ZEISS Grain Size Color Map Workflow

From the SolutionsLab for visualizing grain size distribution.

Determining grain sizes is a critical analysis to be performed for many sample types due to the fact it can provide insight into a number engineering and mechanical properties such as permeability, strength, and expansivity. As a way to help visualize the grain size distribution in a sample, a color mapping feature has been added onto the existing ZEISS Grain Size Analysis workflows that use the intercept, comparison, or planimetric method. The graphic provides positional information on grain size density and is helpful in finding patterns or anomalies in grain size distributions.
