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.

The influence of AlFeSi and Mg2Si phases on corrosion behaviour of the cast 6061 aluminium alloy was investigated. Scanning Kelvin probe force microscopy (SKPFM), electron probe microanalysis (EPMA), and in situ observations by confocal laser scanning microscopy (CLSM) were used. It was found that Mg2Si phases were anodic relative to the matrix and dissolved preferentially without significantly affecting corrosion propagation. The AlFeSi phases’ influence on 6061 aluminium alloy local corrosion was greater than that of the Mg2Si phases. The corroded region width reached five times that of the AlFeSi phase, and the accelerating effect was terminated as the AlFeSi dissolved.
