Abstract
Abstract At present, extreme cases of intercrystalline rupture at high temperatures in non-equilibrium crystallizing alloys (built-up layers) are clearly distinguished. Solidifying cracks are formed in enriched inter-axial and inter-dendritic areas at the moment when the latter are in a liquid state. This type of destruction is associated with crystallization of the last portions of the liquid phase enriched with low-melting alloying elements and impurities and is observed in alloys, where the second phase in the form of eutectics and chemical compounds is formed directly during the crystallization process. Subsolidus cracks, which are most often formed in single-phase alloys with a narrow temperature interval of crystallization, not in liquid intercrystalline interlayers, but after solidification of the last portions of the liquid phase, i.e. below the temperature of the real solidus.
