Abstract
Abstract The dynamic recrystallisation behaviour of high-titaniumcontent 6061 aluminium alloy was investigated by hot compression tests within the temperature range of 623- 783 K and at strain rates of 0.01 -10 s-1. The characteristics of the true stress-strain curves acquired in the hot compression tests were investigated, and it was observed that the dynamic recrystallisation of high-titanium-content 6061 aluminium alloy occurs within the range of deformation temperatures of 623 -783 K, with strain rates of 0.001 - 0.1 s-1as evinced by a physically-based constitutive analysis. The kinetic model of dynamic recrystallisation was deduced to describe the dynamic recrystallisation behaviour of high-titanium-content 6061 aluminium alloy, and the dynamic recrystallisation grain size model was also constructed.
