5. Conclusions
- The Ca in AZX611 only contributed to the formation of Al2Ca precipitate at the temperature 723 K, lowering the Al concentration in the matrix. Due to the Al2Ca, AZX611 showed higher flow stress than that of AZ61.
- Dynamic recrystallization occurred in every alloy during the deformation, Al2Ca induced the PSN effect, and because of the coarse grain size of the initial state, different types of recrystallization textures were separated from each other.
- The dislocation glide mechanism dominated the deformation behavior in the high strain rate condition in this study and the basal texture strengthened. However, in AZX611, newly recrystallized grains formed by the PSN effect had a different texture that can weaken the basal texture.
- The non-basal component of PSN texture occurred during the dislocation glide mechanism, and it was similar with the texture component formed in the solute atom drag mechanism.
