| Abstract Scope |
Refractory metals are commonly used in actinide pyrometallurgy due to their excellent compatibility with molten chloride salt. Due to this being a batch process, equipment failures during pyrometallurgical processing can be costly. Failures are hypothesized to be caused by variations in the manufacturing process, and not the pyroprocessing environment.
For this work, tungsten failure mechanisms were investigated by exposing samples to cerium and molten chloride salts in a simulated plutonium pyrometallurgy environment. These exposures were performed at 850C for 100hr, and then strained to failure to measure if the exposures affected their mechanical properties. There is not a significant change after the exposures. This shows the durability of tungsten, as well as tungsten sensitivity to changes in manufacturing processes. Lower rolling reductions lead to smaller grains that show a decrease in strength, but an increase in ductility. |
