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 975 40 s = 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.
Replacement of copper during production of current-conducting busbars by aluminium clad with a thin layer of copper allows reducing metal intensity of products preserving the high electric conductivity. The technology of manufacture of coaxial copper-aluminium current-conducting rods using explosion welding and drawing was offered. The modes of heat treatment of rods after drawing were experimentally selected providing the required mechanical properties at a minimum number of forming intermetallics. The methods of calculation of sizes of initial billets providing obtaining the required geometric parameters of a product were described. The possibility of application of explosion reduction of billets instead of explosion welding is shown. 5 Ref., 2 Tables, 7 Figures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
