摘要

研究了高锰铝青铜ZCuMn12Al8Fe3Ni2中夹杂物的种类和形态。用不同的过滤介质:刚玉球、高铝砖、焦宝石、烧石等

对高锰铝青铜进行了过滤试验

结果表明:过滤对除去高锰铝青铜中的夹杂物有明显效果

材料的疲劳性能可提高41.3％

延伸率最好的可提高9.7％

抗拉强度略有提高。

Abstract

In high-manganese aluminium bronze

there are micro-inclusions such as alundum

mullite and spinel; and micro-inclusions such as Al2O3

MnS FeS and FeO MnO. Different filtrating mediums have been used in purifying process

including corundum spheres and alumina bricks. The results show that the filtration process provides an excellent effect on eliminating inclusions in the molten metal. Fatigue strength of the material can be raised by 41.8% and elongation by 9. 7% ; while tensile strength can slightly be improved.
