摘　　要：通过掠入射X射线衍射及面探扫描实验研究了经氮离子注入后,6061铝合金表层的晶粒取向.结果表明离子注入对铝合金表层的晶粒取向有较大影响,并且随着注入时间的增加,其晶粒取向也发生变化.同时对离子注入层中晶粒取向的形成进行了探讨.The grain orientation of the 6061 aluminum alloy surface layers implanted by nitrogen ion was investigated by means of grazing incidence X-ray diffraction and X-ray plane detector scan. The results indicate that ion implantation has great effect on the grain orientation of aluminum alloy surface, and the grain orientation varies with increasing implantation time. The reason of the of formation grain orientation in the ion implantation surface layer was discussed.
