摘　　要：影响2A10铝合金铆钉线材组织和性能的因素很多,铸锭质量、拉拔工艺和退火工艺等是重要因素。为解决用户用线材镦制铆钉过程中出现的开裂问题,本项目从合金成分控制、熔铸工艺、挤压工艺,尤其是线材拉拔和中间退火工艺进行了试验研究,得到了合适的工艺参数,生产的线材满足了用户的要求。The ingot quality, the drawing process and the annealing process are important among various factors influencing the microstructure and performance of 2A10 aluminum rivet wire. There are cracks on the rivet which is upset with the wire by the user. To solve this problem, the experiment is carried out on the alloy composition control, the melting and casting processes, the extrusion process, especially the wire drawing and the annealing processes. As such, proper parameters are determined and users are satisfied with the wire.
