What is inclusion metallography
Metal or non-metallic objects that have an obvious interface with the substrate and differ greatly in performance are called inclusions.
According to the nature of inclusions, it can be divided into two types: metallic inclusions and non-metallic inclusions. Metal inclusions refer to the primary crystals of various metal compounds that are insoluble in the base metal and the unmelted high melting point pure metal particles and foreign dissimilar metals; non-metallic inclusions include oxides, sulfides, carbides, fluxes, slag, coatings, and furnace linings Debris and silicate, etc.
According to the different sources of inclusions, endogenous inclusions and exogenous inclusions can be divided. Endogenous inclusions may exist in a free state or in a state combined with the base metal to form a compound, or they may be a combination of multiple impurities.
