【摘要】：采用X射线衍射和电子背散射衍射研究了第二相析出对冷轧AA3003铝合金再结晶织构的影响.当退火温度为783 K时,由于退火温度高,AA3003合金再结晶织构不明显.而在相同退火条件下,在添加了0.39%钪的AA3003合金中发现了强烈的P{011}〈111〉织构.采用EBSD分析再结晶初期的合金,发现2种合金的再结晶形核均无明显择优取向.第二相颗粒析出先于或与再结晶同时发生时,会显著阻碍除P取向晶核之外的再结晶晶核的长大,导致P取向的再结晶晶核长大速度明显快于其他取向的晶核.因此,在并发沉淀析出影响的AA3003合金中形成了强烈的P{011}〈111〉再结晶织构.
[Abstract]:The effect of second phase precipitation on recrystallization texture of cold-rolled AA3003 aluminum alloy was studied by X-ray diffraction and electron backscattering diffraction.When annealing temperature is 783K, recrystallization texture of AA3003 alloy is not obvious due to high annealing temperature.Under the same annealing conditions, strong P {011} < 111> texture was found in the AA3003 alloy with 0.39% scandium addition.EBSD analysis showed that the recrystallization nucleation of the two alloys was not preferentially oriented in the early stage of recrystallization.The precipitation of the second phase particles before or at the same time with the recrystallization will significantly hinder the growth of the recrystallized nuclei except the P-oriented nuclei, resulting in the growth rate of the P-oriented recrystallized nuclei is much faster than that of the other orientations.Therefore, a strong P {011} < 111> recrystallization texture was formed in the AA3003 alloy which was influenced by precipitation.
