Astm: E562-19e1

: For 3D-printed parts, the standard helps identify unwanted phases or oxides that could lead to premature failure under load. Summary of ASTM E562-19e1 Description

Determine the volume fraction of phases (e.g., ferrite, austenite, martensite) in opaque specimens. Methodology Systematic manual point counting using a grid. Common Materials astm e562-19e1

ASTM E562-19e1 is a standard test method developed by the American Society for Testing and Materials (ASTM) that provides a procedure for point counting by random manual point counting. This method involves using a microscope to count the number of points that fall on a specific phase or feature within a material's microstructure. The standard was last updated in 2019 and includes the e1 designation, which indicates that it is an editorially corrected version. : For 3D-printed parts, the standard helps identify

By repeating this process over multiple randomly selected fields, the ratio of points falling on a phase to the total number of points provides an unbiased estimate of that phase's volume fraction. Common Materials ASTM E562-19e1 is a standard test
