Abstract : Micro-structural evaluation of aluminum 6063 extruded by equal channel angular extrusion (ECAE) method is the purpose of this research. Aluminum alloy (AA6063) bar was annealed at 3500C for 1hr, machined and cut to billets size of 14mm x 14mm x 44mm. these specimens for extrusions were machined to the specified dimension to a visibly good finish. The billets were extruded through ECAE die of 14 x 14mm2 channel cross-section areas, the channel angle was 1200 and the extrusion pressures at which samples with different lubricants extruded were noted and recorded. The punch and container used for the experiment were made of tool steel alloy AISI D2. Four lubricants used in this study include; palm oil, olive oil, coconut oil and groundnut oil. The micro structural analysis of the material extruded with palm oil as lubricant, which gave the least extrusion pressure, produced best grain structures followed by groundnut oil and coconut oil while olive oil was the least. However, palm oil and olive oil has better load reduction than other lubricants. All the lubricants tested greatly enhanced microstructures of A1 6063 and can effectively replace the chemical based lubricants used in forging operations.
