Metallography

The Metallo module provides efficient tools for metallography analysis of cast iron or steel. It enables grain detection, structure phase measurement and more.

The Metallography Module consists of two partial modules: the Grain Size Module and the Cast Iron Module.

Grain Size Analysis Module. Main Features of the Grain Size Analysis Module:

  • Measurement of single-phase structures (e.g. Austenite, Ferrite, Alluminium).

  • Measurement of two-phase structures (e.g. Ferrite-Austenite, Ferrite-Pearlite, Ferrite-Martensite).

  • Planimetric, Linear, Circular, and Abrams measurement methods.

  • Customization of the predefined measurement procedures.

  • Support of ASTM and JIS standards (ASTM E112-96, ASTM E1382-97, JISG0551).

  • Easy data export.

Cast Iron Analysis Module. Main Features of the Cast Iron Analysis Module:

  • Graphite classification according to ISO/ASTM/JIS standards (ISO 945, ASTM A247-06, JIS G5502).

  • Ferrite/pearlite ratio measurement.

  • Customization of the predefined measurement procedures.

  • Easy data export.

Metallo Module Features. 

Detection

The application allows you to select one of the predefined structure types and type of the detection. There are several detection types available. You can choose the most suitable one according to the structure types. You can also define the preprocessing and postprocessing operations which will be applied to the image.

Measurement

Measurement methods use test mask with custom editable dimensions. You can choose an ISO/ASTM/JIS standard to treat the results. The Cast Iron Module includes Shape Classifiers based on the ISO/ASTM/JIS standards. While using the Grain Size Module, you can make an advantage of four available measurement methods: Planimetric, Linear, Circular, and Abrams. Once you have set the detection and measurement options, the measurement will be performed and the results will be written to the data table. The detected grains or intersections with grain borders are indicated inside the image. In case the measurement needs some corrections, you find the proper tools just at hand. If you need to process more images, you can put them in one folder and measure them sequentially.

Analysis

You can overview all the data in one window. The central portion of the window contains statistics on all fields of the currently selected measurement method. An additional table where overall statistics (Mean, Standard Deviation, Minimum, Maximum) are displayed is available, too. Optionally, you can create a histogram of the displayed data.
