: Uses a point grid superimposed on a microstructural section to estimate the relative amount of specific phases (e.g., ferrite or sigma phase in duplex stainless steel).
: Count if the point falls exactly on the boundary of the phase. Data Collection
: It provides a reliable alternative to automatic image analysis (governed by ASTM E1245 ) when specialized software is unavailable. Where to Access the PDF
Importance for engineering practice
The significance of ASTM E562:19 lies in its ability to offer a standardized methodology for quantifying the microstructure of materials. This is essential for understanding material properties, predicting performance, and ensuring quality control in manufacturing processes. The standard helps in:
