Metallurgical Testing Service

Metallurgical testing plays a critical role in all metal industries, enabling the precise quantification of metallic properties alongside Chemical and/or Mechanical Testing. Metallurgical Testing is essential for determining the characteristics, integrity, and performance of metals, making it a vital part of quality control and product development processes.

At MPPL, our Metallurgical Testing Service offers comprehensive evaluations, including Metallographic analysis for grain size measurement, microstructure analysis, and non-metallic inclusion rating. The accuracy of these tests is driven not only by state-of-the-art, optimally calibrated instruments but also by the expertise and experience of our metallurgists.

Microscope-based Evaluation

Our Microscope-based testing methods utilize high-powered optical or electron microscopes to examine the sub-surface structures and fine details of materials. These techniques are critical for detecting material characteristics at a microstructural level. Sample preparation is vital, with care taken during sectioning and polishing, followed by acid etching to reveal the material's microstructure.

We offer a range of microscope-based testing services, including:

Coating thickness measurement by microscope:

Accurate evaluation of coating layers to ensure protection and performance.

Decarburization depth measurement by microscope:

Quantifying surface decarburization to assess the material's wear and fatigue resistance.

Carburization depth measurement by microscope:

Measuring the depth of carburized layers for hardness and durability analysis.

Graphite nodularity analysis:

Ensuring proper nodularity in cast iron, a key indicator of mechanical properties.

Macro etch analysis:

Examination of large-scale structural features to detect flow patterns and potential defects.

Grain Flow analysis:

Assessing grain orientation, a crucial factor in determining mechanical strength.

Microstructure evaluation:

Detailed analysis of material phases and microstructures, critical for performance prediction.

Weld evaluation:

Inspection of welded joints for integrity, microstructure uniformity, and defect identification.

Near-surface examination

Detailed examination of the material's surface for detecting imperfections or deviations.

Through a combination of cutting-edge technology and extensive technical expertise, MPPL’s Metallurgical Testing ensures reliable results and helps manufacturers maintain the highest levels of quality in their metal products.
