摘　　要：利用万能试验机(UTM)和冷场发射扫描电镜(SEM)研究不同铝含量对铅合金室温再结晶行为的影响.结果发现,Al元素的添加能有效提高铅合金的力学性能并影响其再结晶行为.当添加0.05%的Al时,铅合金的再结晶及晶粒长大行为受到明显抑制,抗拉强度由13.2 MPa升高至17.9 MPa,随着进一步增加Al含量至0.10%,这种抑制行为逐渐减弱,而合金的强度也由17.9 MPa降低至15.5 MPa.The effect of aluminum content on the re-crystallization behavior of lead was studied by applying uni-versal testing machine and cold cathode field emission scanning microscope. The results show that the addition of Al can affect the lead＇s re-crystallization behavior and improve its tensile strength. When the content of Al is 0.05%, the re-crystallization behavior is inhibited obviously and the tensile strength increases from 13.2 MPa to 17.9 MPa. However, when Al content is increased to 0.10 %, the inhibition effect weakens, and the tensile strength declines from 17.9 MPa to 15.5 MPa.
