Abstract

Present study concerns assessment of nanomechanical property in the bulk Al(65)Cu(20)Ti(15) alloy with varying microstructure synthesized by consolidation of mechanically alloyed powder at different temperature. The microstructure after consolidation at room temperature and 500 degrees C exhibits completely amorphous and nanocrystalline states respectively. Nanoindentation experiments suggest that the maximum strength and hardness values are achieved in the sample sintered at 450 degrees C. The corresponding microstructure revealed dispersion of nanocrystalline intermetallic phase (<50 nm) in the amorphous matrix. (C) 2011 Elsevier BM. All rights reserved.
