Документ Іnvestigation of the causes of the crimination of turbine castings after operation of 100 thousands hours(Харківський національний автомобільно-дорожній універститет, 2024) Tkachenko, D.; Ткаченко, Д. М.One of the most important tasks of power engineering is to increase the reliability and performance of turbine parts. In our work, the research material was casting of a steam distribution housing made of steel 15Х2М2ФБС turbine Pridneprovskaya state district power station after operating 100 thousand hours. One of the main factors preventing the formation of a stone-like fracture is the purity of steel and, above all, the absence of sulfides and nitrides.
