An investigation was conducted to determine the corrosion resistance of various materials to lithium at 1000 to 1900 deg F in static and dynamic systems. Evaluation of test results was based primarily on metallographic examination, weight-change data, dimensional changes, and chemical analyses. The static tests were conducted in constant-temperature systems at 1500 to 1900 deg F for time periods of 100 to 400 hr. Pure metals, alloys, and ceramics were included in the studies. Good corrosion resistance in static systems was exhibited by Be, Cr, Co, Fe, Re, Ti, and Zr; by Co- and Fe-base alloys; and by the ceramic carbides of Cr, Ti, and Zr. Materials which showed promise in static tests and which were available in the form of tubing or pipe were tested in dynamic systems containing temperature gradients. Lithium flow velocities of 1 to 8 ft/min and temperature differences of 100 to 600 deg F between hot and cold sections were used. Hot- zone temperatures ranged from 1000 to 1900 deg F and test periods varied between 100 and 3000 hr. Inconel, stainless steels, and zirconium were the materials studied. Only zirconium was found to be satisfactory at hot-zone temperatures of at least 1500 deg F. Other results and discussions are included. (auth)
