SELECTION OF QUENCHING CONDITIONS FOR THE KHN56MBYUD ALLOY OF ELECTROSLAG REMELTING

In connection with the emergence of new areas of technology, the need to use high-temperature-strength nickel-based dispersion-hardened allo ys has arisen as materials for large-scale structural components. Beca use of the absence of fairly powerful and efficient forge presses and rolling mills, the possibility of applying cast materials without any subsequent deformation becomes one of the determining factors for its selection. For high-load components in the structures of nuclear power plants with gaseous heat carriers, a promising structural material is the KhN56MBYuD (EK-62) nickel alloy. In this paper, we examine the pr operties of this alloy after various heat treatments.
