TL;DR: In this paper, two Al-Mg-Mn alloys having similar compositions but with and without Zr addition were subjected to equal channel angular pressing (ECAP) at 350°C using route Bc and a 90° die, followed by water quenching or air cooling.
Abstract: Two Al–Mg–Mn alloys having similar compositions but with and without Zr addition were subjected to equal channel angular pressing (ECAP) at 350 °C using route Bc and a 90° die, followed by water quenching or air cooling. A series of annealing experiments were conducted at various temperatures from 400 to 460 °C on the water-quenched alloys. Fine structures with grain sizes of about 1–2 μm were obtained in these alloys after six passes. The water-quenched alloy containing Zr exhibited finer structure and higher strength compared to the Zr-free alloy in the same cooling condition, which was due to the existence of Al 3 Zr dispersoids. And in air cooling condition, the difference of strength between these two alloys increased further. This was because that the static recovery and static recrystallization during the air cooling process decreased the strength of the Zr-free alloy, while the fine Al 3 Zr dispersoids inhibited the restoration in the alloy containing Zr. In addition, in the annealing experiments, secondary recrystallization took place in the Zr-free alloy annealed at 410 °C for 1 h, and it was completed when annealed at 460 °C for 1 h. While the alloy containing Zr kept stable up to 460 °C for the pinning effect of the Al 3 Zr dispersoids. Tensile tests showed that the strength of the Zr-free alloy decreased dramatically after annealing at 460 °C for 1 h, while the alloy containing Zr exhibited almost no decline at the same condition.
