General Topic V: Virtual poster session


In this work, open-cell nickel foam was fabricated by a conventional electroplating method on a polymeric foam. Then, the as-plated foams were exposed to an inert sintering atmosphere at 600, 800 and, 1000℃. The sintering treatment was performed to eliminate polymeric substrate and internal stress arising from the nature of the electroplating process. The optical microscopic photos from etched samples showed that the microstructure is remarkably affected by sintering temperature. Recrystallization and grain growth occurred for all sintered samples. In addition, the microstructure of sintered foams at 800 and 1000℃ illustrate some sub-boundaries. These sub-boundaries could be attributed to the formation of annealing twins during grain growth. Microhardness results reveal that the lowest hardness belongs to the sintered specimen at 600℃. By increasing the heat treatment temperature, the microhardness increases as well so that the hardness reaches to that of as-plated foam. This is due to the effect of annealing twins on mechanical properties.
