Query: Automated Image Analysis and Contiguity Estimation for Liquid Phase
  Sintered Tungsten Heavy Alloys   In this study an automated software model using digital image processing
techniques is proposed for extracting the image characteristics and contiguity
of liquid phase sintered tungsten heavy alloys. The developed model takes a
typical image as input and processes it with no human intervention and provides
the corresponding image characteristics and contiguity value. The image
processing algorithm includes segmentation, binding point extraction, phase
connection, particle count and contiguity estimation stages. For the output,
microstructural parameters such as tungsten particle size, amount of tungsten
phase and contiguity are determined. The model is implemented by using 6
different scanning electron microscope images of liquid phase sintered
90W-7Ni-3Fe and 93W-4.9Ni-2.1Fe allloys. The results indicate that relative to
the manual measurements, the automated model can correctly estimate the
contiguity with an error in the vicinity of 5.6% - 2.9% for these two alloys.
The developed software can easily be adapted to be used for other
microstructures. It is also provided as open-source and available for other
researchers.
