【摘要】 采用取向分布函数(ODF)分析并研究了6111铝合金在冷轧过程中织构的演变及轧制工艺对冷轧织构的影响.结果表明,6111铝合金冷轧后,主要轧制织构组分均为Copper织构组分、S织构组分和Brass织构组分;冷轧过程中,在一定条件下会产生较强的旋转立方织构,而且继续轧制时,随着轧板的减薄,旋转立方织构会迅速减弱而Copper,Brass,S等正常轧制织构组分迅速增强.此外,在总轧制形变量相同的条件下,随着道次压下率的提高,轧制织构减弱.更多还原

【Abstract】 The texture evolvement of aluminum alloy 6111 and how the rolling schedule affects the texture during cold rolling were investigated by means of the orientation distribution function(ODF).The results showed that the texture of cold rolled sheet are mainly composed of copper,brass and S components.If the pass reduction and total reduction are both given in cold rolling process,the sheets have cube+ND45 orientation {001}〈110〉 as the main texture component.But,if the rolling process goes on,the orientation intensity of cube+ND45 component decreased rapidly,whereas that of the normal deformation texture including,copper,brass and S components increase with the thinning sheet.In addition,the orientation intensities of the deformation components decrease with increasing percentage pass reduction under the condition that the total reduction remains unchanged.更多还原
