Grain Characteristics of 1235 Aluminum Alloy during Rolling

Grain characteristics of rolled 1235 aluminum alloy were studied by EBSD. The effects of hot rolling, cold rolling and rolling deformation on grain boundaries and grain size of the metal were studied as well. The content of high-angle boundaries was low by 16.48 % in 50 % hot-rolled 1235 aluminum al...

Summary:Grain characteristics of rolled 1235 aluminum alloy were studied by EBSD. The effects of hot rolling, cold rolling and rolling deformation on grain boundaries and grain size of the metal were studied as well. The content of high-angle boundaries was low by 16.48 % in 50 % hot-rolled 1235 aluminum alloy. The complete dynamic recrystallization occurred, and grains were coarse. During 90 % hot rolling, the low-angle boundaries turned into high-angle boundaries constantly. The content of high-angle boundaries was higher by 40.16 %. Coarse grains broke into fine grains, and grew into medium grains. In the 90 % cold-rolled alloy, the trace shape of high-angle boundary was irregular. The lattice distortion was large, providing the energy needed in recrystallization during recrystallization annealing.
