Research abstract

1The purpose of this effort is to develop a technique for protecting Hastelloy S from corrosion caused by liquid lithium. This can be achieved by coating the Hastelloy S with a refractory metal (tantalum, molybdenum, and tungsten). Northwest Technical Industries proposes to use explosive welding to metallurgically bond a thin layer of tantalum, molybdenum and tungsten to Hastelloy S. The objectives of this effort are: 1. Determine the parameters required for explosively welding tungsten to Hastelloy S. 2. Determine the parameters required for explosively welding molybdenum to Hastelloy S, and 3. Determine the parameters required for explosively welding tantalum to Hastelloy S, and 4. Perform ultrasonic testing on each material sample. To accomplish each objective several interations of each material combination will be required to obtain the optimum parameters.
