Cemented Carbide Analysis
Cemented carbides (WC-Co composites) rely on cobalt (3–30 wt%) to balance hardness and toughness. The DX-9700HC evaluates magnetic properties to:
- Determine non-alloyed cobalt content (non-magnetic phase).
- Assess metallurgical bond quality and detect undesired phases.
- Correlate coercivity (Hcj) with grain size: Higher Hcj indicates finer grains.
Measurement Process
- Samples are placed in custom clamps (size-adjustable) within an embedded-sensor coil.
- A Hall probe slot ensures precise field monitoring.
Software Integration: 9700SW Suite
The dedicated 9700SW software streamlines operations with:
- Automated measurement protocols and real-time guidance.
- Curve comparison tools for multi-sample analysis.
- Statistical evaluation and database management.
- Customizable print-ready reports.
- Error alerts and adaptive calibration prompts.
Applications
- Research: Microstructure analysis, alloy optimization.
- Production: Quality assurance, phase detection.
- Metallurgy: Grain size estimation, process validation.
By integrating speed, precision, and compliance, the DX-9700HC sets a benchmark for magnetic property analysis in advanced materials.
