Fabrication and Characterization of the Modified EV31-Based Metal Matrix Nanocomposites

Metal matrix nanocomposites (MMNCs) with high specific strength have been of interest for numerous researchers. In the current study, Mg reinforced AlN nanoparticles were produced using mechanical stirring-assisted casting method. Microstructure, hardness, physical, thermal and electrical properties composites characterized in this work. According to microstructural evaluations, ceramic uniformly dispersed within by applying a stirring. At higher contents, however, some agglomerates observed as consequence particle-pushing mechanism during solidification. Microhardness results showed slight improvement following addition nanoparticles. Interestingly, nanocomposite samples featured conductivities, which can be attributed structural effect matrix. Moreover, expansion analysis indicated that presence lowered Coefficient Thermal Expansion (CTE) case nanocomposites. All all, combination properties, including strength, conductivity, together low CTE, make these new very promising materials electro packaging applications.
