The composite materials studied in this work were pure Aluminium reinforced by TZ-3Y20A particles with different percentage 0,5,10,15 and 20 weight percent. The particle size of TZ-3Y20A was 25µm. The starting materials were examined by SEM, and XRD techniques and optical microscopy. Spherical shape is observed for TZ-3Y20A powder and irregular shape particles were observed for Al powder. SEM photos also, show the shape of, 0%, 5% 10%, 15 and 20% Al-TZ-3Y20A powder milled for 24hr particle powder where the mixed powder became smaller and irregular for percentage of TZ-3Y20A powder increasing. The composite materials were investigated by hardness test which reveal the increase of hardness as the particles percentage increase. The results show that an increase in ultimate tensile strength in specimen with TZ-3Y20A particles, then a decrease in ultimate tensile strength as the percentage of TZ-3Y20A particles increase. The wear test reveals an increase in wear resistance as TZ-3Y20A particles percentage increase.

“…Pada penelitian ini proses sintering dilakukan pada suhu 1000°C selama 2 jam didalam furnace atau tungku pemanas seperti yang ditunjukan pada Gambar 2.17. Semakin homogen material yang tercampur selama proses mixing, maka kekerasan material yang dihasilkan semakin besar (Kargul et al, 2018;Triyanto et al, 2021). Ketika campuran serbuk memiliki distribusi ukuran partikel yang seragam dengan tingkat homogenitas yang tinggi digunakan sebagai bahan baku pada pembuatan komposit atau keramik, akan menghasilkan mechanical strength yang tinggi dan struktur mikro yang terdistribusi secara homogen (Oh et al, 1998).…”

Proses pencampuran perlu dilakukan untuk mencegah terjadinya agglomeration sehingga dapat meningkatkan kualiatas dari produk crucible. Pencampuran adalah proses mencampurkan satu atau lebih bahan dengan menambahkan satu bahan ke bahan lainnya sehingga membuat suatu bentuk yang seragam. Oleh sebab itu, diperlukan suatu kajian untuk mengetahui pengaruh durasi pencampuran terhadap sifat mekanik pada material crucible yang dihasilkan. Spesimen crucible dibuat dengan mencampurkan semen tahan api, limbah evaporation boats, dan kaolin dengan komposisi tertentu. Proses pencampuran bahan dilakukan selama 30, 60 dan 90 menit dengan penambahan air sebanyak 15% dari total berat material. Proses kompaksi dilakukan dengan tekanan sebesar 40 kg/cm . Spesimen yang terbentuk didiamkan pada suhu 30°C selama 7 hari sebelum di sintering. Proses sintering dilakukan pada suhu 1000°C selama 2 jam menggunakan furnace untuk menghasilkan produk akhir. Proses karakterisasi pada penelitian ini menggunakan pengujian kekerasan dan foto makro. Hasil penelitian ini menunjukan spesimen dengan durasi mixing yang paling lama (90 menit) memiliki kekersan yang paling tinggi dikarenakan campuran bahan yang dihasilkan lebih homogen dibandingkan spesimen yang lain.

“…Nano-sized reinforcement particles are much more efficient in enhancing the mechanical properties of Cu matrix composites than micro-sized particles (Panda et al, 2014). However, reducing the size of the reinforcement particles lowers the electrical and thermal conductivities of Cu matrix composites (Kargul et al, 2018). While maintaining the positive effect of nanoparticles on mechanical properties, their negative effect on electrical and thermal conductivity can be eliminated by using reinforcement particles with higher conductivity.…”

The effects of lanthanum hexaboride (LaB6) nano-particles on the electrical, thermal, and mechanical properties of copper-based nanocomposites (Cu-LaB6) produced using microwave sintering (MS) and spark plasma sintering (SPS) processes were investigated in this study. Nano LaB6 particles reduced the electrical conductivity of Cu matrix nanocomposites produced via MS and SPS by 20% and 13%, respectively. Cu-LaB6 nanocomposites had lower thermal conductivity than unreinforced Cu. The electrical and thermal conductivities of the Cu-LaB6 nanocomposite produced by the SPS process were higher than those of the Cu-LaB6 nanocomposite produced by the MS process. An equation that takes particle volume ratio and porosity into account was developed to predict the thermal conductivity of nanocomposites from their electrical conductivity. The calculated thermal conductivity values for Cu-LaB6 nanocomposites were very close to the experimental results. Cu-LaB6 nanocomposites had much higher hardness and compressive strength by 49% and 38%, respectively, compared to those of unreinforced Cu. The hardness and compressive strength of the Cu-LaB6 nanocomposite produced by SPS were higher than those of the Cu-LaB6 nanocomposite manufactured via MS. Although nano LaB6 reinforcement particles reduced the electrical and thermal conductivities of Cu, Cu-LaB6 nanocomposite having high hardness and compressive strength were produced by combining the positive influences of nano LaB6 reinforcement particles and the SPS process.
