摘　　要：借助SEM、EBSD、EDS等测试手段,研究了轧制变形量对含0.5%B的6063铝合金的晶粒取向、形变织构以及再结晶的影响。结果表明:随着轧制变形量的增加,晶粒越来越细小,越来越扁平,晶粒取向趋于一致,小角度晶界密度增加。轧制变形可以明显改变铝合金内部织构占比,合金随着压下量的增加,S织构和Brass织构占比变少,Cube织构和Goss织构的占比变多。均匀化热处理会使样品的再结晶晶粒增加至87.4%,轧制会使再结晶晶粒数量急剧下降,但是随着变形量的增加,再结晶晶粒数量会缓慢增加至1.18%。With the help of SEM,EBSD,EDS and other test methods,the effects of rolling deformation amount on the grain orientation,deformation texture and recrystallization of 6063 aluminum alloy containing 0.5%B were studied.The results show that with the increase of rolling deformation amount,the grains become smaller and smaller,more and more flat,the grain orientation tends to be consistent,and the density of grain boundary with small angles increases.Rolling deformation can significantly change the proportion of internal texture of aluminum alloy,and the proportion of S texture and Brass texture becomes less with the increase of the deformation amount of the alloys,and the proportion of Cube texture and Goss texture becomes more.Homogenizing heat treatment increases the recrystallization grains of the sample to 87.4%,and rolling can reduce the number of recrystallization grains sharply,but the number of recrystallization grains slowly increases to 1.18%as the deformation amount increases.
