Grain Size in Medium-Carbon Steel
One medium-carbon steel image is submitted for analysis. The absence of clear grain boundaries of the pearlitic-ferritic microsctructure with both dark and light phases make traditional thresholding difficult. A machine-learning algorithm specially developed for pearlitic steel allows a reliable one-step detection.

CLEMEX SOLUTION FOR PEARLITIC-FERRITIC GRAINS
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.
