Grain size in austenitic steel
One austenitic stainless steel image is submitted for analysis. Etch stains, polishing artifacts, and carbide precipitates in the grain or at grain edges make traditional thresholding inconsistent. A machine-learning algorithm specifically developed for austenitic grains allows a reliable one-step segmentation.

Clemex solution for Grain Size in Austenitic Steel
Solution
Reproducible detection and measurement of grain size as per ASTM E112 was performed using Clemex Vision image analysis software calibrated with a NIST-traceable stage micrometer.
Results
ASTM E112 grain size measurements are performed. Results are cumulated for automated statistics and graph generation. Final results can be printed directly from Clemex Vision. Raw data are linked to their respective objects and can be exported in Excel format.
