摘要：Equal Channel Angular Pressing (ECAP) is a metal forming technique used to produce Ultra-Fine Grainmicrostructure through severe plastic deformation. This experimental study involves subjecting the pure Aluminiumsamples processed by powder metallurgy route to conventional hot extrusion at a temperature of 400°C, followed byECAP at room temperature via processing route A and route C using a die having channel angle of 110° for 2 passes.Microstructure studies and Hardness measurements were carried out and it was observed that after subjecting thesamples to ECAP, the grains are slightly elongated; whereas it was found to be equi-axed before processing by ECAP.The refinement of the grains and the hardness of the samples are found to increase with multiple passes which complieswith the studies carried out using the commercial Al samples. The present study aims at observing the densificationbehavior along with the development of refined grains after ECAP in materials processed by powder metallurgytechnique since there is no considerable literature regarding processing of pure aluminium through P/M route.Materials processed by P/M technique will find high recognition in future and hence their property enhancement willbe an important area of research
