Ferrite/Pearlite Analysis
The Cast Iron Extension also enables quick and easy determination of the Ferrite/Pearlite ratio in a variety of samples. With two different techniques available to determine the graphite content of the material, the user has the flexibility to chose that most suited to their application.

		Key Features
		Graphite-corrected phase analysis of ferrite and pearlite – in percent Display of results as an overlay to the image and as a spreadsheet Automatic creation of compliant report Standard supported: EN ISO 945, ASTM E247 and JIS G5502 Specifications: Description: Determines the ferrite/perlite ratio Supported Standards: EN ISO 945, ASTM E247, JIS G5502 Measurement Types : Automatic measurement (grey scale threshold setting automatic or manual) Report/OutputReport/Output: Spreadsheet ( Ferrite [%], Perlite [%])

	Settings Both techniques are available by selecting the ‘Graphite Fraction’ icon. The first method requires the user to input the graphite content, if available from other measurements. The second technique uses the graphite content measured from the analysis of spherical graphite. Before the analysis begins, the user must select accurate thresholds so as the lighter coloured ferrite components are easily identifiable from the darker graphite/pearlite phase.
	Execution Ferrite/pearlite analysis is initiated with the simple click of the “Ferrite/Pearlite” icon. The ratio is then automatically determined and transferred into the results spreadsheet. As with the spherical graphite, measurements can be accumulated for multiple samples and subsequently reported in a single datasheet. To analyse any further images, the user simply needs to click on the ‘Next Image’ icon.
	Result The report sheet lists the image names and the percentage of Ferrite and Pearlite present. A summary is automatically generated at the end of the analysis, which includes the average values of all the measurements along with an optional diagram of the information.
