Macro & Microstructure Analysis

      Metallographic examination to analysis the quality of steel, Cast Iron, Non-Ferrous and to analysis on the failure/damage equipment. This method can use for evaluation of quality of metal in term of qualitative.

Macrostructure analysis : the maximum of magnification at x30.

> Image method: 2D, 3D, EFI and movie record

> Measurement: Can be perform the measurement on 2D and 3D

>>2D can be measure of Width, Length, and Angle

>>3D can be measure of Width, High, Length, และ Angle Macrostructure analysis: the maximum of magnification at x30

Machine capacity: Brand: Olympus Zoom: 1X – 30X

TEST METHODS/SPECIFICATIONS

• ASTM E340
• ASTM E381
  

Graphite Analysis

     The type of graphite of graphite form has influent of the physical property of cast iron. The classification can help to evaluation of quality of cast iron.

Grain Flow Analysis

      To examine the directional or orientation of metal grains and any inclusions that have been deformed by forging. 

Determining Volume Analysis

      Estimating the volume fraction of an identifiable constituent or phase from sections through the microstructure

Grain Size number

      The size of grains plays an important role in the characteristics of the material ranging from increasing mechanical properties such as yield strength and tensile strength

Method of grain size measurement ASTM E112:

1.Comparison procedure

2.Planimetric procedure

3.Intercept procedure

Positive Material Identification (PMI)

A variety of PMI test methods are available to determine the identity of alloy materials. The primary methods include portable X-ray fluorescence, portable optical emission spectroscopy.

Optical Emission Spectrometry (OES)

• Providing quick grade ID and sorting of ferrous and nonferrous samples
• Accurate analysis materials including Carbon, Phosphorus, Sulphur, Boron and Tin
• Service capacity:

         - Ferrous            - Ni-Base

Standard of Test

Scanning Electron Microscope (SEM)/Energy dispersive X-Ray Spectrometer (EDS)

      Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX) is the best known and most widely-used of the surface analytical techniques. High resolution images of surface topography, with excellent depth of field, are produced using a highly-focused, scanning (primary) electron beam combined with the ability to generate localized chemical information (EDS)

Fracture analysis (Qualitative)

Microstructure (Cross section)

>Secondary Image

>Back Scatter Image

Composition analysis (Quantitative)

> Mapping

> Line scan

> Point/Area analysis
