Abstract

Energy transfer from reacting thermites placed on a v-notch steel target was evaluated for two thermite compositions which were Boron with Iron (III) Oxide (B-Fe₂O₃) and Aluminum with Iron (III) Oxide (Al-Fe₂O₃). A high-speed infrared camera captured a temporally evolving temperature distribution on the substrate as the thermite reaction self propagated. Results quantified the percent of the overall energy available from the chemical reaction that was transferred into the substrate and lost via other heat transfer modes. Results showed the B-Fe₂O ₃ reaction transferred 53% of its heat of reaction into the steel substrate compared to 11% for Al-Fe₂O₃.
