In this work, the influence of the metallographic preparation and the image acquisition conditions on the quantification of secondary phases by a multilayer perceptron neural network was investigated. The images were obtained by scanning electron microscopy (SEM) from Ni-based superalloy coatings on C-Mn steel deposited by gas tungsten arc welding (GTAW) cold wire process. The results showed that excessive chem...
Quantitative metallography is a technique to determine and correlate the microstructures of materials with their properties and behavior. Generic commercial image processing and analysis software packages have been used to quantify material phases from metallographic images. However, these all-purpose solutions also have some drawbacks, particularly when applied to segmentation of material phases. To overcome s...
