Measurement of single-phase structures (e.g. Austenite, Aluminium).
Measurement of two-phase structures (e.g. Ferrite-Austenite, Ferrite-Pearlite).
Planimetric, Linear, Circular, Abrams and Comparison Charts measurement methods.
Customization of the predefined measurement procedures.
Support of various industrial standards.
Easy data export.
The Grain Size module is compliant with the following standards:
ASTM E112-13 (2013)
ASTM E1382-97(2015)
ISO 643 (2012)
JIS G0551 (2013)
GB/T 6394(2017)
See also Application of the Standards in the Planimetric Method.
There are the following methods implemented in the application:
The grain size is calculated from the number of grains detected in the measured area.
The grain size is calculated from the number and length of intercepts of the detected grains with the measurement mask.
Depending on the method and the standard, the Grain Size number (GS) is determined either as a result of an arithmetic expression or by assigning the closest GS value listed in the standard.
There are two main modes of measurement in the application:
The operator controls every step of the measurement process – image selection, detection settings, method settings. Manual corrections of the detected grains/intercepts are allowed. Multiple individual measurements can be merged together in order to get the GS from a higher number of measured fields unless the method and the standard remain unchanged. Custom settings of the detection or the method can be saved as presets. See Direct Mode.
It is designed for automated measurement. A complete preset of the detection and the measurement method is created and then applied to any number of images. Once started, changes or corrections are not possible. See Wizard Mode
