Ferrite and Pearlite Content Analysis

Problem solved:
The solution evaluates the relative share of pearlite and ferrite on the etched samples of cast iron. The analysis is preceded by determining the share of graphite on the unetched sample.

Solution:
When the graphite content is measured, the sample is etched to reveal phase differences (done separately). Captured image of the etched sample is contrasted to make ferrite bright, while pearlite becomes dark. All bright areas on the binary image obtained by applying Threshold segmentation operation are considered to be ferrite. Several operations are used to remove noise and pores from the image. Chain of operations is finalized with Apply mask of pearlite bounds, which demonstrates the results of selecting fractions. 

Determined parameters:
The solution produces the series of parameters, including the analyzed area, content of graphite and ferrite, expressed in % whole, the error of determining ferrite content, and the content of pearlite to content of ferrite ratio grade.

This solution is ordered separately. Installed SIMAGIS®  platform is required for the solution to function.
