摘　　要：结合微量元素在5083铝合金中的作用,尤其是Zr、V在均匀化退火过程中的析出特点、细化作用及对高温拉伸塑性的影响,同时本着降低原料成本的原则,设计了三种成分的5083铝合金进行试验。A合金是用高纯铝为原料熔铸的5083铝合金中加入微量的Zr、V;B合金是在普通的5083铝合金中加入Zr、V;C合金是普通5083铝合金。通过高温拉伸试验和金相、电镜等显微组织观察分析,并探讨微量元素的细化作用,以提高5083铝合金板材超塑性能。The experiment was carried on 5083 aluminum alloys with three different contents of chemical compositions in line with the principle of reducing raw material costs based on the effect of trace elements in 5083 aluminum alloy（ especially Zr and V,due to their precipitation characteristics in homogenization,refinement,and influence on tensile plasticity at high temperatures）. Alloy A is 5083 aluminum alloy cast from high purity aluminum,with a trace of Zr and V. Alloy B is ordinary 5083 aluminum alloy with a trace of Zr and V. Alloy C is ordinary 5083 aluminum alloy. The refining effect of trace elements is researched and the superplasticity of 5083 Al-alloy sheet is improved by tensile tests at high temperatures,metallographic microstructure and SEM observation.
