中文摘要：

用X射线衍射ODF分析方法解析了在电场时效过程中2014铝合金织构的形成和演变机理．结果表明：在电场时效过程中2014铝合金的主织构始终是{001}〈210〉织构，而非电场时效其主织构随着时效时间的延长由{001}〈210〉织构（6h和8h）转变为{001}〈100〉立方织构（10h），然后由{001}〈100〉立方织构转变为{011}〈100〉织构（12h）．这主要是电场时效降低了固溶处理2014铝合金样品的储存能，从而抑制其回复所致．

英文摘要：

The mechanism of texture formation and evolution for 2014 aluminium alloy during an electric field aging was investigated by X-Ray ODF analysis. The results show that the main texture components of the samples aged under the electric field is unchangeably the {001}（210） component. In constrast, the main texture of the samples aged without an electric field change from {001}（210）（6 h and 8 h） to {001}（100） cube component （10 h） and then to {011}（100）（12 In） with the increase of the aging time. This is mainly due to the decrease of stored energy of the solid solution by the applied electric field, which accordingly restrains the recovery of the 2014 aluminum alloy.
