    Influence of Cold Rolling Process on Plastic Strain Ratio of 1100 Aluminum Alloy Plates and Earring Ratio of Cup-shaped Parts

      摘要
    • 摘要: 采用拉伸试验测定了三种不同冷轧工艺生产的1100铝合金板的塑性应变比,并通过各向异性分布函数对其进行了拟合处理;同时采用晶体取向分布函数(ODF)对其织构进行了检测,最后与拉深试验中的制耳率进行了对比,确定了合理冷轧生产工艺.结果表明:不同工艺生产的板材的拉伸性能表现出不同的各向异性,从而产生不同的制耳,其中尤以塑性应变比对制耳的影响最为明显;当冷轧生产工艺采用(550～580) ℃×16 h中间退火时,通过改变织构组分及比例降低了板材的各向异性,满足了板材拉深杯形件对制耳率的要求.

       

      Abstract: Tensile test was performed to get different plastic strain ratios of 1100 aluminum alloy plates caused by three kinds of cold rolling process,which were treated with fitting processing based on the anisotropic distribution function,the texture was detected by means of the orientation distribution functions (ODF) and compared with the earring ratio of final cup-shaped parts.A reasonable cold rolling process of 1100 aluminum alloy plates was determined.The results show that the tensile properties of the plates exhibited obvious anisotropy with different production processes.The plastic strain ratio showed the most obvious effect on earning.When the mid-annealing at (550-580) ℃ for 16 h was adopted during the cold rolling process,the anisotropy of plates was reduced by adjusting texture composition and proportion,and the plates could meet the requirement of earring ratio for cup-shaped parts.
