摘要

Different milling conditions have been tried to produce nanoparticles of TiB_2 to be used as reinforcement in Al matrix composite materials. The milling of TiB_2 compounds leads to a decrease of both the crystallite size and the particle size. Moreover, we demonstrate that the use of optimized conditions with a vibratory miller allows - in a short period of time - the direct synthesis of nanoparticles of TiB_2 starting from the elemental powders (Ti and B). Then TiB_2 reinforced Al composite was fabricated using a simple powder metallurgy process followed by free sintering under controlled atmosphere. The influence of (ⅰ) the nanometric TiB_2 particles grain size and (ⅱ) their volume fraction on the hardness and Young's modulus, measured from nanoindentation tests, has been analyzed.
