Microstructural and mechanical characterization of Al6061-ZrB2 nanocomposites fabricated by powder metallurgy
Al6061-ZrB2-reinforced metal matrix nanocomposites were synthesized through the hot pressed process (PM) with varying the nano ZrB2 content in wt% (0, 0.5, 1, 1.5, and 2) and studied their microstructural and mechanical properties. Mechanical properties such as hardness, compression strength, tensil...

| description | Al6061-ZrB2-reinforced metal matrix nanocomposites were synthesized through the hot pressed process (PM) with varying the nano ZrB2 content in wt% (0, 0.5, 1, 1.5, and 2) and studied their microstructural and mechanical properties. Mechanical properties such as hardness, compression strength, tensile strength, and yield strength were investigated for the fabricated composites. Field emission scanning electron microscope (FESEM) microstructural characterization of the PM samples revealed a uniform distribution of ZrB2 nanoparticles in the matrix. X-ray diffraction (XRD) analysis confirmed the presence of aluminum and ZrB2 particulates in the Al-metal-matrix composites. The incorporation of ZrB2 particles into the Al matrix was shown to significantly enhance the microhardness of the fabricated nanocomposites by 11%. In addition, the incorporation of ZrB₂ reinforcements in the aluminum alloy significantly enhanced the compressive, yield, and tensile strengths of the AMCs. The density of composites was significantly influenced by the presence of ZrB2 particulates. The best composite among the fabricated composites was identified as Al6061-2wt% ZrB2. |
