Abstract
According to the algorithm of a developed comprehensive analytical solution method (CASM), a new cast high-temperature corrosion-resistant nickel alloy ZhS3LS-М has been developed for manufacture of all-cast nozzle appliances. The developed alloy is characterized by the high-temperature strength s40975 = 180–200 MPa at the level of the industrial non-corrosion-resistant alloy VZhL12E as well as technological weldability and corrosion resistance at the level of commercial weldable corrosion-resistant alloy ZhS3LS. 24 Ref., 11 Tables, 1 Figure.
Keywords: cast high-temperature nickel alloys; performance parameters; CASM-method; regression model; regression equation; service properties, technological weldability
