Abstract

Referring to 5052 alloy, a new Al-Fe-Mn wrought aluminum alloy was developed by removing Mg and adjusting the content of Fe, Mn, Cr and rare earth elements, and the effects of precipitate and texture on PLC (Portevin-Le Chatelier) effect of the two aluminum alloys were studied. The results show that a strong rolling texture Brass{110}〈112〉 was formed in 5052 alloy, which produced an obvious PLC effect, and the interaction between a large amount of fine Mg₂Al₃ phase precipitated in the alloy and dislocation made the PLC effect stronger first and then weaker with increasing plastic strain. The Al-Fe-Mn alloy was mainly composed of recrystallized texture Cube{001}〈100〉, resulting in high plasticity of the alloy, and the FeAl₃ precipitate with larger size had relatively weak pinning effect on dislocation, and no PLC effect occurred in the alloy.
