Calibration
Each microscope objective used with a digital camera requires calibration, which should be completed after full hardware installation. Any adjustment or replacement of components necessitates recalibration.
Measurement
Gain precise measurement control with the Measurement module—draw directly on traces, shapes, or outlines, and instantly record results in a worksheet. Export, print, or save your data for easy analysis and reporting.
Grain Size
The module enables fast, reliable, and repeatable grain size analysis compliant with standards like ASTM E112, E93, and E1181. It supports assessment of both ferritic and austenitic steel grain structures.
A comprehensive set of analysis techniques is included:
- Lineal Intercept Method
- Abrams Three-Circle Method
- Snyder & Graft Method
- Comparison Method
- Random Intercept Method
- Manual Grain Size
The built-in analysis wizard quickly calculates grain number, mean grain area, and mean intercept length based on the selected method.
Segmentation
The Segmentation module identifies and quantifies material phases by partitioning images based on grayscale intensity. Users define phases via a histogram, ensuring accurate detection.
Each phase is displayed with a unique color overlay, allowing simultaneous visualization. Preprocessing filters like Despeckle and Smoothing enhance accuracy. Both segmented images and data are saved for clear phase analysis.
HISTOGRAM
Upon launching the module, a grayscale histogram is automatically generated. The X-axis represents intensity values (0–255), while the Y-axis shows the number of pixels at each level. The system supports standard industry analysis.
Users can define up to ten threshold levels to identify and label different phases, with each phase assigned a unique color between the selected thresholds.
INTENSITY DISPLAY
The current intensity range of the selected phase is shown in real time within the dialog box, allowing for quick adjustments and precise control.
SELECTED PHASE ANALYSIS
By clicking within the histogram, users can determine the percentage area of a specific intensity range. For accurate results, previous selections must be cleared, and preview mode should be set to “None.”
Porosity
Due to distinct contrast, pores are readily identified. This module applies grayscale thresholding for automatic porosity analysis in compliance with ASTM B276. Pores appear as red-highlighted regions within bitplanes for clear visibility.
The system reports total pore count and detailed size distribution, including min/max values as percentages. The process is fully automated, delivering consistent and precise results.
Ductile Iron/Nodularity
Ductile Iron—also referred to as Nodular Cast Iron, Spheroidal Graphite Iron, or SG Iron—is a type of cast iron characterized by its graphite-rich microstructure. This module utilizes advanced image processing techniques, including global thresholding, boundary detection, and artificial neural networks, to deliver accurate microstructural analysis.
Nodules touching image boundaries are excluded, and any features smaller than 10 microns are automatically filtered out. Nodules and non-nodules are classified based on predefined spheroidicity parameters.
Automated Measurements Include:
- Nodule Count
- Nodule Size (classified using Arabic numerals 1 to 8)
- Nodule Form (classified using Roman numerals I to VI)
All measurements are completed automatically with a single click.
In the second phase of analysis, etched samples are evaluated. The system calculates the percentage of Graphite and Pearlite present in the structure. Results from both etched and non-etched samples are compiled directly into a spreadsheet within the software interface.
Comprehensive reports—with detailed data and associated images—are generated instantly with one click.
Ductile Iron/Nodularity
Gray Iron/Graphite Flakes
Gray Iron, or Gray Cast Iron, features a graphite flake microstructure that forms during solidification. Its name derives from the gray appearance of its fracture surface, caused by the presence of graphite.
This module automatically analyzes graphite flakes in gray iron samples using advanced metallographic imaging. Short Type A flakes are typically associated with higher strength and better ductility.
With a single click, the software measures:
- Graphite Flake Length (classified into eight size classes: 1–8)
- Graphite Types (A, B, C, D, E) based on flake orientation and distribution
The analysis complies with ASTM A247-67 and ISO 945-1 standards.
In etched samples, the software calculates the percentage of pearlite by excluding the graphite phase. The final report includes a breakdown of the matrix composition, detailing the proportions of pearlite, ferrite, and graphite.
Detailed reports are auto-generated based on the chosen international standards.
Decarburization
The module evaluates decarburization depth by detecting microstructural variations. Partial decarburization reflects carbon loss without full depletion; complete decarburization reaches the ferritic boundary.
Measurements along the cross-section are accurate and fully compliant with ASTM E1077-91.
Coating Thickness
This module measures plating or coating thickness using a cross-sectional microscopy method. The specimen is sectioned, mounted, polished, and examined under an optical microscope. In some cases, etching the base metal is required to enhance contrast and clearly define the coating layer.
The method evaluates the local thickness of both metal and oxide coatings through precise optical measurement. Under optimal conditions, the system can achieve an accuracy of up to 0.8 microns, making it ideal for analyzing thin coatings with high precision.
Spherodization
This module analyzes spheroidal graphite (nodules) in cast iron samples, classifying features based on predefined spheroidicity criteria. In the visual output, nodules are highlighted in blue, while non-nodules appear in red for easy identification.
Each nodule is automatically classified by:
- Form (Roman numerals I to VI)
- Size (Arabic numerals 1 to 8)
The software also calculates the nodule density, expressed as nodules per square millimeter (nodules/mm²), providing valuable insight into the material's structural quality.
Carbide Banding
Iron carbide, or cementite, is an intermetallic compound composed of iron and carbon. It naturally forms in steels and cast irons as part of the microstructure. In addition to occurring during conventional processing, iron carbide can also be produced as a raw material through the iron carbide process, an alternative iron-making technology.
