Would you like to carry out a metallographic analysis on your samples?

In the laboratory, the technique of determining the structure of a metal alloy by observing it with an optical microscope (OM) after a specific preparation is called metallography. It is an examination by metallographic section. In the analysis of metal alloys, knowledge of the properties of the metallic material requires metallographic study and analysis.

What is a metallographic analysis?

Metallographic analysis, also known as metallographic examination, is a material characterization technique based on their microstructure. It is often used in the metallurgical industry to evaluate the quality, properties, and structure of metals and alloys.

The data collected during metallographic analysis includes information on:

  • chemical composition,
  • crystalline structure,
  • phase and inclusion distribution,
  • as well as material quality.

Interpreting this data can provide valuable insights into the mechanical, electrical, and thermal properties of metallic materials, as well as their resistance to stress, corrosion, and other metallurgical failures.

SEM-EDX

CHNSO Elemental Analyzers

OES

ICP-AES

The metallographic examination or study performed on the prepared surface by Optical Microscopy allows for the determination of the structure, grain size, and the nature and content of inclusions, as well as the identification of any heat treatment or surface treatment.

If necessary, the prepared surface can also be studied by scanning electron microscopy coupled with a microprobe (SEM-EDX) to identify the chemical nature of unknown precipitates and inclusions or to specifically characterize the layering of a surface treatment (e.g., in the case of electroplating coatings).

Metallography in the metallurgy, automotive and foundry sectors

Through metallography, industries can optimize the composition of materials to improve their strength, durability, and ability to withstand extreme environmental conditions.

By measuring and quantifying these parameters, industries can optimize their materials in a variety of industries, from automotive parts production to electronics manufacturing. In short, metallographic analysis is an essential step in the quality control and development process for new materials.

FAQ

What is metallography testing?

 Metallography testing involves preparing and analyzing metal samples under the microscope to study microstructural features like grains, phases, and inclusions. It offers essential insights into how materials will perform in real-world applications.

Why is metallography testing important?

Because microstructural characteristics directly affect mechanical and chemical properties—such as strength, corrosion resistance, and fatigue life—understanding them is vital for quality control, material certification, and failure analysis.

What techniques are used in metallography testing?

Typical procedures include cutting, mounting, polishing, etching, followed by optical or electron microscopy (SEM/TEM) to capture high-detail visuals of microstructure.

Can you identify defects through metallography testing?

Absolutely. We can detect material defects such as inclusions, porosity, grain irregularities, and phase transformations—critical information for ensuring component reliability.

Which industries benefit from metallography testing services?

We serve aerospace, automotive, energy, precision manufacturing, and R&D sectors—any field where understanding microstructure is key to product performance and compliance.
