The Clemex Grain Size Module
Built to Handle Real-World Samples
Conventional grain size methods struggle with imperfect samples. Clemex AI-powered grain size module is built to handle the full spectrum of microstructural complexity, across all grain morphologies, materials, and preparation conditions. Advanced deep learning models detect grain boundaries reliably, regardless of etching quality, surface artifacts, or structural irregularities, making grain size analysis faster, simpler, and more accurate than ever.
Complex Morphologies
Twins
Twin boundaries are often misidentified as grain boundaries, inflating grain count.
Clemex Studio-trained models distinguish twins from true grain boundaries with precision.
Over-Etching
Excessive etching obscures grain boundaries, making accurate detection unreliable.
Clemex Vision AI reconstructs boundaries from partial signals for consistent measurement.
Scratches
Surface scratches mimic grain boundaries and disrupt automated segmentation.
Clemex AI empowered detection filters artifact lines, preserving only genuine microstructural boundaries.
Pores
Porosity interrupts grain boundary continuity, fragmenting grains artificially.
Clemex AI fills boundary gaps around pores, ensuring complete and accurate grain detection.
Compression Slip Lines
Dense slip lines create false internal structures that confuse standard detection algorithms.
Clemex Studio models are trained to ignore slip features and isolate true grain boundaries.
Banding Grain Size
Alternating coarse and fine grain bands require detection across different size scales simultaneously.
Clemex Vision handles multi-scale grain populations, reporting accurate size distributions per band.

Frequently Asked Questions
Does the solution require manual parameter adjustment for each sample type?
No. Clemex's grain size module is fully plug-and-play. Unlike solutions that require users to manually set thresholds, adjust contrast parameters, or retrain models per sample type, our module requires zero configuration. The AI model was trained across a wide range of materials and preparation conditions and is ready to apply from day one.
How does your AI handle twins, slip bands, porosity, banding, and over-etched samples?
Traditional threshold-based and even some AI-assisted methods fail on complex microstructures like twinned austenite, slip bands, porosity, banding, or poorly etched surfaces. Clemex's deep learning model was specifically trained on these difficult cases. It recognizes morphological context rather than relying on intensity values alone, enabling robust detection even on imperfect samples.
Is the solution ASTM E112 compliant? How is compliance ensured?
Yes. Clemex's grain size module is fully compliant with ASTM E112. Compliance is built into the analysis pipeline: measurement methodology, intercept counting, and G-number calculation all follow ASTM E112 specifications. Every generated report includes the standard reference and traceable methodology for audit purposes.
Can it handle multiple materials: steel, stainless, copper, ceramics, and others?
Yes. The Clemex model supports a broad range of materials including carbon and low-alloy steels, stainless steels (austenitic, ferritic, martensitic, duplex), copper, austenitic alloys, mixed pearlite/ferrite microstructures, and ceramics (alumina, zirconia, sintered materials), all within the same module, without switching models or reconfiguring settings.
How does repeatability compare to manual or semi-automated methods?
Manual grain size measurement is inherently operator-dependent. Clemex's fully automated approach removes operator subjectivity entirely: the same image always produces the same result, regardless of who runs the analysis, on what machine, or at what time.
Does it work with our existing microscope hardware?
Clemex is hardware-agnostic. The grain size module integrates with a wide range of metallographic microscope brands and camera setups. There is no proprietary hardware requirement or lock-in. If your microscope produces standard digital images, Clemex can analyze them.
How long does implementation and onboarding take?
Because the Clemex grain size module requires no model training, no parameter configuration, and no custom setup per material, implementation is fast. Most labs are fully operational within hours of installation. Our team provides onboarding support and documentation in multiple languages.
