Fe-P-C-Cu系合金的性能及其烧结后的尺寸收缩

本文讨论了不同的配铜量、配碳量及烧结温度对Fe-P-C-Cu系合金性能及其烧结后的尺寸收缩的影响规律。通过试验得出,采取Fe-0.6%P-1.9%C-0.7-1.0%Cu幻成分配比,以及在1090-1110℃温度保温2.5小时的烧结工艺条件下,可得到较满意的结果。本文还结合目行车车铃齿轮产品对Fe-P-C-Cu与Fe-C-Cu系合金的性能及烧结舌约尺寸收缩进行了试验对比。

THE PROPERTIES OF Fe-P-C-Cu SYSTEM ALLOYS AND THEIR SIZE SHRINKAGE AFTER SINTERING

This article deals with the effect of the different amounts of copper and carbon additions and sintering temperature on the properties of Fe-P-C-Cu system alloys and their size shrinkage after sintering. It is shown experimentally that the satisfactory results will be obtained, if the composition of the alloy is Fe-0.6%P-1.9%C-0.7~1.0% Cu which is sintered at 1090~1110℃ for 2.5h. The experimental contrast of the properties and size shrinkage between Fe-P-C-Cu alloys and Fe-C-Cu alloys was made when these alloys were used in making bicycle bell gears.
