摘要

借助SEM、XRD等现代分析技术分析了Sb含量为0.4%时对镁合金组织和力学性能的影响

研究了Sb对镁合金的强化机理。结果表明

Sb可以细化AZ91D镁合金的组织、改善Mg17Al12相形态和分布

并生成新的强化相Mg3Sb2;Sb在稀土阻燃镁合金中

可以减少棒状Al11RE3相

并形成颗粒状CeSb相

使镁合金的抗拉强度提高。

Abstract

The effects of 0.4% Sb on the microstructure and mechanical properties of Mg alloy and the strengthening mechanism of Sb were investigated by means of SEM and XRD.It was revealed that tensile strength of AZ91D Mg with 0.4%Sb alloy can be increased by 20MPa due to refining structure of AZ91D Mg alloy

improving the morphology and distribution of the Mg

phase and forming a new enhancing Mg

phase.The tensile strength of ignition-proof Mg alloy with 0.4% Sb can be increased by 64 MPa due to the decrease of bar-like Al

phase and the formation of particle CeSb phase.
