Equal channel angular pressing (ECAP) is a novel technique for producing ultra fine grain structures in submicron level by introducing a large amount of shear strain into the materials without changing the billet shape or ...

The effect of charcoal on the grain refinement and mechanical properties of the AZ91 is investigated in the present study. The results show addition of 0.4 wt% charcoal produced maximum grain refinement in the AZ91 Mg alloy ...
