CHORD METHOD OF EVALUATING SURFACE MICROSTRUCTURAL CHARACTERISTICS
1984-10-01
HISTORICAL
ARP1820
This practice provides a method of evaluating microhardness and microstructure very close to the surface. It is useful for process control in heat treatment of steel parts to detect nitriding and carburization as well as decarburization and excessive intergranular oxidation. It also may be valuable for other evaluations, e.g., plated coatings and other materials.

ARP1820C
This practice provides a method for evaluating microhardness and microstructure very close (0.002 inch (0.051 mm) or less) to the surface of a disk specimen. Specific accept/reject criteria for partial decarburization (3.7.1), inadvertent carburization/nitriding (3.7.3), total decarburization/intergranular oxidation (3.8), and other characteristics evaluated are to be found in the applicable specification where this ARP is referenced.
