description: This work is devoted to the study of the causes of crack formation in austenitic steel grade 08Ð¥18Ð10Ð¢ and the development of technology to improve the quality of large-sized forgings. During the research, the following tasks were solved: - Investigation of the causes of crack formation in austenitic steel grade 08Ð¥18Ð10Ð¢; - Development of homogenization annealing technology, which ensures a reduction in cracking and grain dispersion in forgings made of austenitic steel grade 08Ð¥18Ð10Ð¢; - Reduced grain variation. The work was carried out on the basis of the Prometey Central Research Institute of Mechanical Engineering, where the microstructure of defective forgings with cracks was examined. As a result of the research, it was found that with an increase in the mass of the ingot, cracks form at earlier stages of forging, which could be associated with an insufficient duration of homogenization annealing. Based on the established data, a homogenization annealing regime was developed, which made it possible to reduce crack defects and also improve the quality of large-sized forgings.
