Flake size in gray cast iron as per ASTM A247
Images of gray cast iron with different sizes of flakes are submitted for characterization and size classification according to ASTM A247.
Figure 1. Part of the original image captured at 100X (1.27 µm/pixel).
Figure 2. Outline view of flakes as measured. Note that the longest flake was first part of a group of flakes.
PURPOSE
Demonstrate the ability of the Clemex Vision image analysis can measure the maximum size (length) of flakes size and find the longest one. The methods and operations used are discussed in the report linked at the bottom of this page (click the Download PDF link below).
RESULTS
Length measurement is performed on each distinct feature from red bitplane. Automated statistics and graph are generated and would be cumulated when analyzing several images. Final results can be printed directly from Clemex Vision. Raw data are linked to their respective objects for validation purpose. Raw data can also be exported in Excel format allowing to build an automated macro to find the size class.
