一、剪切结构的原因
1、 Reason for shear structure
1. 一般冷轧1060铝板的储能约为2000kPa;退火过程中再结晶之前,强回收组织的存储容量可降低到300kPa。
1. Generally, the energy storage capacity of cold rolled 1060 Aluminum sheet is about 2000 kPa; before recrystallization during annealing, the storage capacity of strong recovery structure can be reduced to 300 kPa. A kind of
2. 而少量的残余弹性能量中央谷物可以忽略,表面颗粒的弹性能量占1% ~ 3%的存储能量,这将不可避免地导致的差异中央的复苏和再结晶行为和表面颗粒,值得关注。
2. A small amount of residual elastic energy in the central grain can be ignored, and the elastic energy of the surface particles accounts for 1% - 3% of the storage energy, which will inevitably lead to the recovery and recrystallization behavior of the different central and surface particles, which deserves attention.

测试观察,并根据外部负载和晶粒间应力反应,结合理论计算表明,大道率轧制铝板在时间的压力下会导致辊在铝板表面引起的高剪切应力的压力比次方乘以足够高,以便相应的剪切应力引起的辊缝区轧制应力状态的横向挠度超过40°角,铝板表面会形成剪切纹理,纹理和中心层仍属正常轧制辊缝表面的滑动,滑动带差动滑动摩擦不是板厚度方向应力分布和滚结构重要影响的形成在时间压力下变形速率会引起较强颗粒内的颗粒间的相互作用下的表面残余弹性应变能显著提高,的弹性能也与晶粒取向密切相关,并对随后的反应和再结晶过程产生影响。
According to the test and observation, and according to the external load and the stress response between grains, combined with theoretical calculation, it is shown that the pressure ratio of the high shear stress caused by the roll on the surface of the aluminum plate under the pressure of time will be multiplied by the power to be high enough, so that the transverse deflection of the rolling stress state of the roll gap caused by the corresponding shear stress exceeds 40 ° angle, and the surface of the aluminum plate will form shear texture, The texture and the central layer are still sliding on the surface of the normal rolling roll gap. The differential sliding friction of the sliding belt is not an important influence on the stress distribution in the thickness direction of the plate and the formation of the roll structure. Under the time pressure, the deformation rate will cause the surface residual elastic strain energy to increase significantly under the interaction between the particles in the stronger particles, The elastic energy is also closely related to the grain orientation, and has an effect on the subsequent reaction and recrystallization process.
