Abstract

Abstract: In the investigation reported here, coarse-grained Al powder (85 μm) was subjected to ball milling for 4 h in an attritor at room temperature under argon atmosphere. The bulk aluminium samples consisting of ultrafine and nanocrystalline grains were prepared from ball-milled powders using a high frequency induction sintering machine. The bulk samples were investigated for the enhancement in mechanical properties using uniaxial compression experiments to large strains. Vickers micro hardness measurements were made along the diametral line of the bulk samples. A comparative study on the effect of mechanical properties of bulk samples obtained through different processing conditions was addressed and an optimum processing condition is established. The variation in strain-rate sensitivity with different processing conditions of the bulk samples was also investigated.
