摘要
对Mo-30Cu合金室温拉伸性能进行了研究,并对其断口进行观察分析.通过对Mo-30Cu合金冷轧实验,研究了不同变形量下组织的变化规律.结果表明:Mo-30Cu合金的断裂以Cu相的韧性断裂为主,并伴随着Mo/Cu界面的分离和Mo晶粒的解理断裂.Mo/Cu界面的分离和Mo晶粒的解理断裂是Mo-30Cu合金室温轧制过程中产生裂纹的主要原因.
The room temperature tensile properties of Mo-30Cu alloy was investigated and its fracture morphology was observed Cold rolling test was carried out to study the change in microstructure of Mo-30Cu alloy with different deformations The results showed that the room fracture of Mo-30Cu alloy was composed fracture of copper binder, separation of molybdenum/copper binder interfaces, and cleavage of molybdenum particles. Cleavage of molybdenum particles and separation of molybdenum-copper binder interfaces made cracks in Mo-30Cu alloy during cold rolling at room temperature.
