Corrosion of vanadium alloys in flowing lithium
Description
The objective of this program is to investigate the influence of a flowing lithium environment on the corrosion behavior and mechanical properties of structural alloys under conditions of interest for fusion reactors. Corrosion rates are determined by measuring the weight change and depth of internal corrosive penetration as a function of time and temperature. These measurements, coupled with metallographic evaluation of the alloy surface, are used to establish the mechanism and rate-controlling processes for the corrosion reactions. Initial effort on mechanical properties is focused on fatigue and tensile tests in flowing lithium environment of controlled purity. Corrosion data are presented for several vanadium alloys exposed to flowing lithium at 482 and 4270C. Metallographic evaluation of the exposed specimens is also presented. The influence of alloy composition and exposure conditions on the corrosion behavior of vanadium alloys is discussed. 4 refs., 7 figs., 1 tab
