Microstructure of Cast Irons (by image analysis software)
Microstructure of Cast Irons According to ISO/TR 945-2:2011

• iSolution DT provides shape, size, graphite types, nodularity and distribution of graphite inclusions in cast iron according to international standards such as ASTM A247_2010, ASTM A247-67 (1998), ISO/TR 945-2: 2011, ISO16112: 2006 , JIS G5502 (2001), KSD 4302 (2002).
  
  
• Cast iron analysis considers several consequent image-frames processed to achieve improved statistical results. The results are
  accumulated in a special data collector document. An Excel file may be created to report the results.
  
  
• The real nodularity analysis based on standard Nodularity is calculated by Graphite types. ISO/TR 945-2: 2011 describes procedures using image analysis software for graphite classification.
  
  
• ISO16112: 2006 defines a method of compacted (vermicular) graphite cast iron nodularity evaluation.
  
  
• In ISO 16112:2006, percent nodularity is calculated and weighted based on roundness-shape factor and graphite form. Reference images provided in Chart Navigator (see below) include Nodule Size Class, Flake Size Class, Graphite Form, and Distribution Examples.
