What is microstructure examination?
Examination of the microstructure of a material provides information used to determine if the structural parameters are within certain specifications. Microstructural examination is generally performed using optical or scanning electron microscopes to magnify features of the material under analysis.
What does microstructure analysis reveal?
Microstructure can also be used to predict tool life or even the performance of a particular part, since it can be used to reveal specific properties, such as strength, ductility, corrosion resistance, and other conditions and properties.
How do you observe microstructure?
2.1 The Microstructure Observation Method. Observing the microstructure of self-sensing concrete is a commonly used method to evaluate the mixing/dispersing uniformity of composites (as shown in Figure 3.8). Observation equipment often used includes a scanning electron microscope (SEM) and optical microscope.
What is the required magnification for microscopic structure examination?
Magnifications of x50 and above are used for micro examinations. Intertek has camera and microscopes that cover a range from x1 to x1,500 magnification.
What is the purpose of microstructure?
The microstructure of a material (such as metals, polymers, ceramics or composites) can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low temperature behaviour or wear resistance.
What is macroscopic examination?
Macroscopic Examination, also called Macro Test or Macro Examination, evaluates the quality and consistency of a test sample using only low or no magnification.
Why is microstructure analysis important?
The microstructure of a material can influence its physical properties including corrosion resistance, strength, toughness, ductility, and hardness. These properties help determine how the material will perform in a given application.
How do you do microstructure analysis?
Analytical Techniques
- SEM/EDX (Scanning Electron Microscopy / Energy Dispersive Analysis)
- XRD (X-Ray Diffraction)
- FTIR (Fourier Transform Infrared Analysis)
- WLI (White Light Interferometry)
- Brunauer-Emmett-Teller (BET) Surface Area Analysis and Barrett-Joiner-Halenda (BJH) Pore Size and Volume Analysis.
What are the 5 steps in metallography?
The basic steps for proper metallographic examination include: sampling, specimen preparation (sectioning and cutting, mounting, planar grinding, rough and final polishing, etching), microscopic observation, digital imaging and documentation, and quantitative data extraction through stereological or image analysis …
Which is the main application of microscopic examination?
In urinary tract conditions such as infections, inflammation, and malignancies, more epithelial cells are present. Identification of the type of cells helps the doctor pinpoint where the condition is located. For example, a bladder infection will leave large amounts of transitional epithelial cells in urine sediment.
What is a macroscopic examination?

Why do we use average grain size in microstructure?
Typically the average grain size is used to describe the microstructure [15], but this is not a suitable measure for heterogeneous microstructures. Several investigations [14–20] have shown that the grain size distribution has an effect on the mechanical properties.
Which is the best characterization of grain size?
The relative grain size dispersion characterises the spread of grain size, and is typically within the range of 2.5…6. Small values are seen for annealed base materials, while multiphase and welded microstructures are in the upper range.
How are microstructure examination and hardness test performed?
The laboratory report is about two experiments: Microstructure examination and Hardness test. I n their hardness. The collected data were evaluated and compared among the specimens. The appropriate scale for measuring the hardness of the following specimens were decided in the conclusion.
What are the services of a microstructure laboratory?
Their microstructure analysis services range from simple determination of parameters such as grain size or coating thickness to full evaluation of abnormalities and failure mechanisms such as inclusions, segregation, and surface layers.
