Coupling effect of P, Ni micro-alloying and thermomechanical processing on microstructure evolution and high formability of Al-Mg-Si-Cu-Zn-Fe alloys
Source abstract
Abstract
The coupling effect of P, Ni micro-alloying and thermomechanical processing on the mechanical properties and microstructure evolution of a novel Al-Mg-Si-Cu-Zn-Fe alloy was systematically studied. The results show that, both the P-added and Ni-added alloys exhibit significantly improved formability and strengths due to the changed distribution of multi-scale particles and its effect on recrystallization microstructure. However, when the Ni content reaches 0.1 wt%, unbreakable AlNiFe phase tends to be formed, inducing a strength loss. The formation mechanism of multi-scale particles distribution characteristics and its effects on deformation and recrystallization microstructure of the alloys were deeply discussed. Additionally, the high formability mechanism of P-added and Ni-added alloys have been also put forward. A better understanding of them provides novel visions for the development of Al alloys with high formability.
