Abstract

Al-2wt. % B4C Nano composites were fabricated through three methods i.e. STIR CASTING, POWDER METALLURGY, and MECHANICAL MILLING. In the STIR CASTING method, B4C nanoparticles with 80nm mean particle size were added to the melt and the resulting mixture was poured in a steel mold. In the MECHANICAL MILLING and POWDER METALLURGY methods, after mixing Al and B4C powders, the resulting composite powders were shaped through Cold Isostatic Pressing (CIP). Finally, in all methods, the resulting product was hot extruded. The microstructure of samples was characterized by optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis. In order to compare the mechanical properties, tensile, compression, and hardness tests were performed. Results demonstrated that the nanocomposites prepared by the MECHANICAL MILLING method have the most uniform particle distribution and highest hardness and strength.
