Abstract

Effects of equal-channel angular pressing (ECAP) at 325°C to a strain, e~10 and post-ECAP annealing for 1 hr in the temperature range of 350-520 <sup>o</sup>C on structure of the cast and homogenized Al-Mg-Sc-Zr alloy 01570C were analyzed. It is found that annealing of ECAP processed material containing near homogeneous ultrafine-grained (UFG) structure with ~1 µm grain size led to normal grain growth, accompanied by coarsening of Al3(Sc,Zr) dispersoids. As compared to the cast alloy, the coarsening of dispersoids in the deformed alloy started at lower temperature and occurred more intensely, and resulted in more rapid loss of their coherency with surrounding matrix.
