Effect of Precipitate and Texture on PLC Effect of 5052 Alloy andNew Al-Fe-Mn Wrought Aluminum Alloy
-
摘要: 参考5052合金,通过去除镁元素,调整铁、锰、铬及稀土元素的含量,开发了新型Al-Fe-Mn变形铝合金,研究了析出相和织构对2种铝合金PLC (Portevin-Le Chatelier)效应的影响。结果表明:5052合金中存在强烈轧制织构Brass{110}〈112〉,产生了明显的PLC效应,且合金中大量析出的细小Mg2Al3相与位错相互作用使得PLC效应随塑性应变增加而先强后弱;Al-Fe-Mn合金中再结晶织构Cube{001}〈100〉占主体,使得合金塑性较好,且尺寸较大的FeAl3析出相对位错的钉扎作用较弱,合金未发生PLC效应。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.
