Monolitik magnezyum, nano-TiB2 partikülleri ile takviyelendirilerek Mg-TiB2 nanokompozitleri üretilmiş ve nano-TiB2 partiküllerinin Mg matrisli nanokompozitlerin elektriksel, ısıl ve mekanik özellikleri üzerindeki etkileri incelenmiştir. Monolitik Mg ve Mg-TiB2 nanokompozitler kıvılcım plazma sinterleme yöntemi ile üretilmiştir. Hem analitik hem de deneysel sonuçlar, Mg-TiB2 nanokompozitlerin elektriksel ve ısıl iletkenliklerinin monolitik Mg'den daha düşük olduğunu ve nano-TiB2 partiküllerinin miktarı arttıkça elektriksel ve ısıl iletkenliklerinin azaldığını ortaya koymuştur. Mg-TiB2 nanokompozitlerin deneysel olarak bulunan elektriksel ve ısıl iletkenliklerinin, daha yüksek nano-TiB2 partikül miktarlarında daha yüksek oranda düştüğü saptanmıştır. Belirli miktarda nano-TiB2 partikül içeren Mg-TiB2 nanokompozitlerin deneysel elektriksel ve ısıl iletkenlikleri, analitik hesaplamalar ile elde edilen sonuçlardan daha düşük değerlerde bulunmuştur. Mg-TiB2 nanokompozitlerin basma dayanımları monolitik Mg’den daha yüksek olmakla birlikte, nano-TiB2 partikül miktarı arttıkça basma dayanımı artmış, ancak yüksek miktarda nano-TiB2 partiküllerin kullanılması basma dayanımında azalmaya neden olmuştur. Monolitik Mg ile karşılaştırıldığında, ağırlıkça %1,5 nano-TiB2 partikül içeren Mg-TiB2 nanokompozitinin basma dayanımı %34 artış gösterirken, hasar gerinimi ise %12 azalmıştır.

Electrical, Thermal, and Mechanical Properties of Mg-TiB2 Nanocomposites Produced by Spark Plasma Sintering

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.
