摘要：

In this present work the elemental powders pertaining to composition of Al5083 alloy was milled using planetary ball mill (Insmart systems) for 20 h. The elemental powders are loaded in HSS vial with 10:1 ball to powder ratio at 250 RPM. Various parameters such as crystalline size, particle size and morphology have studied using X-ray diffraction analysis and scanning electron microscopy. The crystallite size of the powders determined using Williamson Hall analysis of XRD is 23 nm after 20 h of milling. These nano crystalline Al-5083 alloy powders were consolidated using ECAP with and without application of back pressure. Physical and mechanical properties such as density and hardness values were measured for sintered and unsintered samples.
