Cast Iron - VDG, EN ISO 945, ASTM
As an extension for the evaluation of spherical graphite, the Cast Iron Materials Extension consists of two parts: the Cast Iron Graphite Analysis offers a fast, accurate and automated classification of spherical graphite, whereas the Cast Iron Ferrite/Pearlite analysis accurately calculates the Ferrite/Pearlite ratio in accordance with accepted standards |

Settings
The user initially needs to define the setting for the graphite analysis, which is initiated simply by clicking on the ‘Settings’ icon. To detect the nodular graphite, users can
decide between automatic or manual threshold determination. The desired standard can be selected from a list of available classifications. User are required to enter the minimum and maximum size classes for inclusions that are desirable in the results spreadsheet. Furthermore, statistical calculations can be defined on the shape of the nodular graphite particles. It is also possible to exclude very small particles which are not relevant for the measurement from the analysis |
|
Execution
The next step is to click on the ‘Graphite Analysis’ icon, which will commence the analysis process and automatically generates a spreadsheet of the resulting data. Further images can be analysed in the same way and each individual measurement result will be added to an overall results spreadsheet. To perform the graphite analysis for all of the images, the user simply needs to click on the ‘Graphite Summary’ icon. A diagram detailing the graphite size distribution is created along with a report, which is in accordance with the standards defined in the settings. |

Results – compliant to EN ISO 945, ASTM E247 and JIS G5502
The measurement report includes the image name, calculated nodularity, area (%) and the number of detected particles, according to the defined standards. For the nodularity and the area, the Cast Iron Materials Extension also calculates the average values, displaying them in a detailed and easy-to-read list. The correct size classification is calculated by weighting the size classes, and usability is increased by the ability to select a different standard or range of size classes without the need to repeat the complete analysis procedure.
