Abstract

Two Al-Mg-Si alloys with different Fe-rich phase contents within a range of low Fe-rich phase content were designed, and the effect of Fe-rich phase on microstructure, texture and mechanical properties of the alloys were studied through microstructure characterization, texture measurement and tensile test. The results show that the shape and size of the Fe-rich phase may undergo continuous changes during thermomechanical processing, especially for the intermediate annealing state, and some coarse particles of Fe-rich phase could become nano-sized; although the introduction of the Fe-rich phase affects the microstructure of the intermediate states slightly during thermomechanical processing, it may be beneficial to efficiently refine the final recrystallization grain structure; Fe-rich phase can affect recrystallization texture and volume fractions, and thus the final weak recrystallization texture may be developed; Fe-rich phase is beneficial to improve yield strength, ultimate tensile strength and plastic strain ratio r, reduce strain hardening exponent n and planar anisotropy coefficient, and keep elongation unchanged. The improvement of properties can be attributed to the fine microstructure and weak texture.
