In the world of materials science and metallurgical engineering, precision is everything. One of the cornerstones of quantifying microstructural features is (officially designated ASTM E562-19 ). This standard test method covers the manual or automatic determination of volume fraction using a systematic manual point count—a critical technique for evaluating phases like porosity, graphite nodules, or inclusions in metals and composites.
