3 Principle of the method
3.1 principle of stereology
Stereology (Stereology), from the two-dimensional section or projection surface image feature parameters to restore (or deduce) three-dimensional image morphology
science. According to the principle of stereology, the two-dimensional parameters measured and calculated on the grinding surface of the metallographic sample can determine the volume of the phase in the three-dimensional space.
fraction.
The stereoscopic exchange formula (1).
VV = AA = LL (1)
Where.
VV - Percentage of particles or fiber volume to be measured,%;
AA - Percentage of particles or fiber area to be measured,%;
LL - Percentage of cut line or fiber cut line,%.
3.2 Principles of Image Analyzer
Through the image segmentation technology and data processing system, automatic measurement of the percentage of reinforced area AA, according to formula (1) VV = AA
Volume of volume to be measured.
3.3 Principle of the microscope
Using a scalable microscope eyepiece to directly measure the particles or fibers of the lens to be measured in the field of view of the microscope,
The ratio of the total length of the line segment cut by the measured reinforcement to the total length of the measured line segment is calculated according to VV = LL in equation (1)
Calculate the volume of the volume to be measured.
4 test equipment
4.1 image analyzer with quantitative measurement and analysis software (area, area percentage) and data processing system.
