Abstrakt: This article describes corrosion and mechanical tests on 1Kh18N9T[lCrl8Ni9Ti] steel specimens previously held in molten lithium (of various degrees of purity) at 700, 800, and 900° C both under isothermal conditions and in the presence of concentration- and heat-induced mass transfer. The results of gravimetric, spectrographic, and metallographic analyses showed that the corrosive action of lithium on the steel studied takes the form of dissolution of steel constituents and intergranular penetration of the steel by molten lithium. The role of nitrogen and oxygen in the corrosion process was estimated and it was established that even weak currents of liquid lithium intensify its corrosive action on 1Kh18N9T steel.
