Astm E562-19e1 Upd May 2026

ASTM E562-19e1 is the current international standard for determining the volume fraction of identifiable phases or constituents in a material's microstructure using the systematic manual point count method. This 2019 edition (with editorial revision 1) provides a rigorous, statistically based framework for metallographers to quantify features like ferrite-to-austenite ratios in stainless steels, martensite content in dual-phase steels, and porosity in additive manufacturing. 1. Fundamental Methodology

ASTM E562-19e1 is particularly critical in industries where phase balance is a safety-critical requirement. astm e562-19e1

applies ASTM E562 (specifically version 01, though the methodology remains consistent) to calculate porosity and pore diameter in additively manufactured components. Etchant Accuracy for Phase Quantification experimental review ASTM E562-19e1 is the current international standard for

To quantify the amount of a specific phase (volume fraction) in a material. Systematic manual point counting using a grid overlay. Importance Systematic manual point counting using a grid overlay

Many researchers use ASTM E562-19e1 to "calibrate" or verify their automated software settings to ensure the computer is seeing the same volume fractions as a human expert. 5. Typical Applications
