摘要 通过添加Sb元素以形成在AX52基体中弥散分布的硬质颗粒,阻碍位错滑移,以进一步提高合金的抗蠕变性能。实验表明,添加Sb可以提高AX52合金的抗蠕变性能,但当w(Sb)>0.3%后,蠕变性能有所下降。 By adding antimony to the alloy, hard particle is formed to prevent dislocation climbing, the creep resistance of the alloy increased further. The experiment results indicate that adding Sb can increase the creep resistance of AX52 alloy, but the creep resistance decreases when w（Sb）〉0.3%.
