Automated vs manual steel microcleanliness
Automated vs manual steel microcleanliness
(OP)
Hi Friends.
I am looking at purchasing a new optical microscope that has automated inclusion analysis (image analysis) per ASTM E45. When the unit was demonstrated, it counted roughly 4X more D-thin inclusions in E45 Method D rating than our metallographer found. Another metallographer from a separate company verified our manual results. This is very typical of what we see with automated versus manual ratings.
Can someone help me to determine:
- Do the automated systems overestimate the ratings?
- Do manual ratings underestimate the inclusion amount?
Thanks in advance!

These are just some thoughts--I don't have experience with these types of automated softwares.
