Özet
Monolithic magnesium was reinforced with nano-TiB2 particles to produce Mg-TiB2 nanocomposites, and the effects of nano-TiB2 particles on the electrical, thermal, and mechanical properties of Mg matrix nanocomposites were studied. Monolithic Mg and Mg-TiB2 nanocomposites were manufactured using spark plasma sintering process. Both analytical and experimental findings revealed that the electrical and thermal conductivities of Mg-TiB2 nanocomposites were lower than those of monolithic Mg and decreased as the amount of nano-TiB2 particles increased. The electrical and thermal conductivities of Mg-TiB2 nanocomposites decreased at a higher rate for a higher weight fraction of nano-TiB2 particles. The experimental electrical and thermal conductivities of Mg-TiB2 nanocomposites at a certain amount of nano-TiB2 particles was measured at lower values than those obtained by analytical calculations. The compressive strength of Mg-TiB2 nanocomposites was higher than that of monolithic Mg and improved as the weight fraction of nano-TiB2 particles increased; however, a high amount of nano-TiB2 particles resulted in a decrease in compressive strength. The compressive strength of Mg-TiB2 nanocomposite with 1.5wt.% nano-TiB2 particles improved by 34%; on the other hand, its failure strain decreased by 12% compared to monolithic Mg.
