Image Analysis for the Metal Industry

In metallography, the microstructure decides whether a material performs, and the measurement has to hold up across operators, shifts and sites. Clemex replaces chart comparison and hand-placed measurements with automated image analysis: standard-referenced results in minutes, reproducible between laboratories, and traceable back to the exact field they came from. From incoming material release to final component qualification, it turns micrographs into decisions you can defend.

Every Metals Measurement, One Platform

Detect and measure your metal microstructures with Clemex Vision and the AI-powered Clemex Studio. Analyse your images manually, semi-automatically with operator validation at defined checkpoints, or fully automatically for unattended production runs. Every analysis module is configurable to your own specifications and acceptance criteria, and all of it is engineered specifically for metallurgy and the metal industry.

Grain Size Analysis

Automated grain size measurement by Jeffries, intercept and comparison methods, reported as ASTM grain size number with full distribution. AI-based segmentation handles twins, incomplete boundaries and preparation artifacts that defeat threshold-only approaches, so etch quality no longer dictates whether a sample can be measured.

Steel · Clemex CIR

Non-Metallic Inclusion Rating

Detects, classifies and rates non-metallic inclusions across the full sample area, assigning type and severity automatically. Worst fields are identified per standard and mapped by inclusion type, long inclusions spanning several fields are measured as one object, and multiple heats and samples can be analysed in a single run with results grouped by heat.

Micro & Macro Hardness Testing

Automated Vickers, Knoop, Brinell and Rockwell testing with machine-measured indentation diagonals, removing the operator variability that dominates manual reading. Supports case-depth and hardness-traverse patterns, converts between scales per ISO 18265, and generates the full indent map and report without transcription.

Duplex & Dual-Phase Steels

Phase Analysis & Volume Fraction

Quantifies area percentage of each constituent, from two-phase black-and-white separations up to multi-phase colour-etched microstructures. Handles the uneven intensity and staining that make delta ferrite, austenite and sigma difficult to threshold, and supports traditional manual point counting alongside automated area measurement for standards that require it.

Castings · Forgings · Powder Metal

Porosity Analysis

Measures pore area percentage, count and size distribution per field, with sphericity and compactness separating round gas porosity from irregular shrinkage cavities and inter-dendritic networks. Grey-level discrimination keeps look-alike features such as graphite nodules, carbides and etch pits out of the result, and every pore is linked to its stage coordinate for relocation.

Ductile & Gray Cast Iron

Graphite Form, Flake Size & Nodularity

Classifies graphite form, size class and distribution type, and computes nodularity percentage in ductile iron. It also computes ferrite, pearlite and carbide percentages. The analysis separates nodules from flakes explicitly rather than by roundness cutoff alone, and reports maximum and mean flake length for gray iron.

Coatings · Carbides · Oxides

Coating & Layer Thickness

Measures thickness on cross-sections from single dense deposits to multilayer stacks, converting each coating body into perpendicular measuring lines for a full thickness distribution rather than a handful of spot readings. Grey-filter and top-hat operations separate adjacent layers that share the same intensity range, and porous thermal-spray coatings are reported with pore area alongside thickness.

Cast Aluminum · Copper Alloys

Dendrite Arm Spacing (DAS / SDAS)

Measures mean linear dendrite spacing and secondary arm spacing to assess local solidification rate and casting quality. Clemex uses a patented method for this measurement, which matters here because DAS is one of the least reproducible metallographic parameters when the counting lines are placed by hand.

Banding & Microstructural Orientation

Quantifies the degree of banding and directional orientation in wrought steel microstructures using directed intercept counts along and across the deformation direction, giving an objective anisotropy index in place of a visual chart comparison.

Decarburized layer depth profiling

Steel · Heat Treatment QC

Depth of Decarburization

Measures the depth of the carbon-depleted surface layer on heat-treated and forged steel, reporting a full depth distribution along the edge rather than a few manual readings. Automated measurement matters here because the transition is gradual and operator judgement of where the affected layer ends is the main source of scatter.

Metal Powders · AM Feedstock

Particle Size & Shape Analysis

Size and morphology distribution for atomized powders and additive manufacturing feedstock, including sphere characterization on SEM images and assessment down to sub-micron sizes. Deep-learning segmentation separates touching and agglomerated particles that threshold methods merge into one object, reporting D10/D50/D90, Feret diameter, circularity and satellite content.

Carbides, Gamma Prime & Hydrides

Characterization routines for second-phase constituents in high-temperature and nuclear alloys: carbide size, area fraction and distribution in nickel-based alloys, gamma prime particle analysis, hydride orientation in zirconium cladding, and dihedral angle in tungsten alloys. These are typically configured per specification through our routine creation service.

Key features

Built for Reproducible Metallography

AI Segmentation Without Coding

Clemex Studio trains a segmentation model by annotation instead of threshold tuning, which is what makes stained etches, incomplete grain boundaries and twinned structures measurable at all. Trained models load directly into Vision for production runs.

Clemex Studio

Multi-Routine, One System

Any number of distinct routines run on the same installation, so grain size, phase, porosity and coating thickness are not separate purchases or separate benches. Routines ship as a library or are built to your specification.

Clemex Vision

Automated Stage Scanning

Motorized stage integration scans defined field patterns across the specimen, logging coverage and field count per run so sampling is defensible rather than wherever the operator happened to look.

Motorized Microscope Stages

Traceable Raw Data

Every measured object is linked to its field and stage coordinate. Any row in the data browser sends the stage back to that exact location, so an out-of-spec result can be re-examined instead of re-run.

Clemex Vision

NIST-Traceable Auto Calibration

Each objective is calibrated automatically against a NIST-traceable stage micrometer, giving accurate and traceable measurements across all magnifications without operator judgement.

Stage Micrometer Slide

Multi-Sample Batch Analysis

Unmounted samples load directly into custom holders and run unattended, with results grouped by heat and sample and individual reports generated per specimen with no manual steps between runs.

Stage Accessories & Sample Holders

Mosaic Reconstruction

Adjacent fields are stitched into a seamless mosaic, so features spanning multiple fields, long inclusions, large flakes, continuous coating interfaces, are measured as single objects rather than truncated at field edges.

Clemex Vision

Standard-Referenced Reporting

Reports generate automatically after each run and are fully customizable: logo, captured fields, distribution graphs, statistics and standard-compliant result tables in one locked PDF.
