Image processing-based analysis of interfacial phases in brazed stainless steel with Ni-based filler metal

This work presents an image processing method to identify the distribution of CrxBy in a brazed joint of SUS304/MBF20/SUS304. Although the chemical compositions at designated locations on such joints can be measured through electron-probe microanalysis (EPMA) and transmission electron microscopy (TEM), determining the overall distribution of CrxBy and quantitatively describing this phase is difficult. Therefore, an image-processing algorithm was...
