Abstract :

Equal Channel Angular Pressing is being carried out to deform the AZ31 alloy at a processing temperature of 633K up to 4 passes for route Bc. In the present work, mechanical properties are enhanced by refining the grain size of AZ31 alloy at 633K for route Bc. The effect of microstructural changes in the AZ31 alloy has been studied resulting improvement of respective passes of mechanical properties illustrated in the present work. The average grain size of the as received material is obtained to be 31.8 μm and it is reduced to be 13.3 μm, 11 μm, 9 μm, and 7 μm after first, second, third and fourth pass respectively. Mechanical properties of AZ31 alloy improved prominently with increase in number ECAP passes at 633K. X-ray diffraction analysis was carried out to understand the phase changes in the AZ31 alloy for before and after ECAP processed specimen.
