Overview
QL Metallurgical Image Analysis Software Suite is a dedicated digital image analysis platform engineered for quantitative microstructural characterization in metallurgical and materials science laboratories. Designed exclusively for integration with QL inverted metallurgical microscopes and compatible third-party imaging systems (via standard USB 3.0 or HDMI video capture), the software implements pixel-based morphometric algorithms compliant with ASTM E112 (grain size determination), ASTM E1245 (inclusion rating), ISO 643 (steel microstructure classification), and GB/T 6394 (Chinese national standard for grain size). It operates on Windows 10/11 (64-bit), supporting real-time acquisition from CMOS/CCD cameras with resolutions up to 5 MP, and delivers calibrated, traceable measurements through user-defined stage calibration using certified reference micrometers.
Key Features
- Multi-tiered Edition Architecture: Four validated editions (A–D) enable progressive functionality scaling—from basic image annotation and report generation (A) to automated ASTM/ISO-compliant phase quantification and statistical reporting (D).
- Calibrated Geometric Metrology: Enables precise measurement of linear dimensions (length, width, diameter), angular features, area fractions, perimeter, circularity, and aspect ratio—each traceable to NIST-traceable calibration standards.
- Standardized Microstructure Assessment: Built-in libraries for ASTM E112 grain sizing, ASTM E1245 nonmetallic inclusion evaluation, ISO 4967 rating charts, and GB/T 10561 inclusion classification support audit-ready compliance documentation.
- Automated Comparative Analysis (Edition D): Utilizes histogram-matched template matching and threshold-adaptive segmentation to perform batch-wise comparison against reference microstructures—reducing inter-operator variability in routine QC inspections.
- GLP-Compliant Data Handling: Supports electronic signatures, audit trails (user actions, timestamps, parameter changes), and encrypted project file storage—meeting baseline requirements for ISO/IEC 17025 and FDA 21 CFR Part 11 Annex 11 readiness.
Sample Compatibility & Compliance
The software processes monochrome and RGB images acquired from polished, etched, or as-cast metallographic specimens—including ferrous alloys (carbon steels, stainless steels, cast irons), non-ferrous metals (aluminum, copper, titanium), and advanced composites. It accepts TIFF, BMP, JPEG, and proprietary RAW formats from QL and select OEM camera modules. All analytical outputs—including grain size distributions, inclusion counts per mm², and phase area percentages—are generated in accordance with internationally recognized metallurgical testing standards. The system supports multi-user role-based access control and generates PDF/Excel reports with embedded metadata (acquisition date, operator ID, microscope model, objective magnification, calibration factor).
Software & Data Management
QL Metallurgical Image Analysis Software employs a modular architecture with centralized database management via SQLite (local deployment) or optional Microsoft SQL Server integration (enterprise licensing). Raw images and processed results are stored in hierarchical project folders with SHA-256 checksum verification. Version-controlled templates allow labs to predefine analysis workflows (e.g., “ASTM E112 Grain Size Protocol v2.1”) and enforce method consistency across shifts. Export options include CSV (for statistical process control), XML (for LIMS integration), and annotated TIFF/PDF (for regulatory submissions). Software updates follow a documented change control process aligned with ISO 9001 Clause 8.5.2.
Applications
- Quantitative grain size analysis in heat-treated steel components per ASTM E112 and ISO 643
- Inclusion rating and morphology classification in bearing steels and aerospace alloys (ASTM E45, ISO 4967)
- Porosity and defect quantification in additive manufactured (AM) metal parts
- Phase fraction analysis in duplex stainless steels and aluminum-silicon eutectics
- Carbide network assessment in tool steels and high-speed steels
- QC/QA documentation for ISO/TS 16949 and AS9100-certified manufacturing lines
FAQ
Which microscope models are officially supported?
QL inverted metallurgical microscopes (models QL-MI500, QL-MI700, QL-MI900) with QL-Cam series digital cameras. Third-party inverted microscopes with U-Dock or C-mount adapters and DCI/USB3 Vision interface are supported via driver certification.
Can the software be validated for GMP environments?
Yes—Edition D includes IQ/OQ documentation templates, electronic signature capability, and full audit trail export, enabling qualification under FDA 21 CFR Part 11 and EU Annex 11 when deployed on validated Windows OS configurations.
Is offline operation permitted for secure lab networks?
Absolutely—the software requires no cloud connectivity or internet access during routine operation. License activation uses hardware-bound dongles or offline activation files.
How is calibration traceability maintained?
Users perform stage calibration using NIST-traceable stage micrometers (e.g., Thorlabs R1L10S, Mitutoyo 12AAAB50); calibration data is embedded in every exported result and archived with project metadata.
What training and technical support options are available?
QL provides on-site installation validation, ASTM/ISO methodology workshops, and annual software maintenance contracts including priority bug resolution, minor version upgrades, and remote troubleshooting via TeamViewer-assisted secure sessions.
