摘要
采用金相显微镜 ,X -射线衍射技术和深冲试验等手段 ,研究了主要生产工艺因素对 310 4铝合金板材织构和制耳行为的影响。结果表明 ,采用适当高的温度大压下率热轧以及在中间退火前小压下率冷轧都可以增加其立方织构 { 10 0 }〈0 0 1〉组分 ,使成品板材中同时具有较强的立方织构 { 10 0 }〈0 0 1〉和变形织构 { 110 }〈112〉 ,深冲时出现 0°/ 90°和 4 5°方向共存的 8个小制耳 ,降低制耳率 ,减小各向异性。
The effects of the main processes on texture and earing of 3104 aluminum alloy sheet are investigated with the help of electron microscopy,X ray diffractometry and deep drawing.The results show thats the increase of ｛100｝〈001〉 cubic texture content is achieved by adopting hot rolling of high temperature and deforming degree and cold rolling of low deforming degree before mid annealing.Because of existing a strong ｛100｝〈001〉 cubic texture and ｛110｝〈112〉 texture in finished sheet and having eight small earings at the rolling derection,90° direction,45° direction during its deep drawing,the decreases of earing ratio and anisotropy are obtained.
