A Comparison of the Corrosion and Stress Corrosion Resistance of Two Depleted Uranium Alloys; DU-0.75 Ti and DU-2 Mo

Abstract

Considerable experimental work concerning the corrosion rates, stress corrosion behavior, and effects of corrosion on the mechanical properties of depleted uranium alloys has been performed. In this study data for two alloys, DU-0.75 Ti and DU-2 Mo, in three environments have been collected and compared in order to determine whether there are significant differences in their corrosion characteristics and whether these differences warrant a choice of alloy for kinetic energy penetrator applications. In moist air the corrosion rates of the two alloys are low and appear to be of little consequence with respect to this application. In salt fog the corrosion rate of DU-3/4 Ti increases sharply. The weight loss in thirty days is about 7% of the total weight. No data was found for the molybdenum alloy in salt fog. Further experimental work is suggested.
