在相同的制备工艺（压制、烧结、旋锻、拉拔）下，采用碳、氧、铁、镍元素含量不同的钼粉分别制备出两种φ0.18 mm的钼丝，对其成形过程和成品的显微组织和力学性能进行分析对比。结果表明，杂质元素含量降低，将显著净化晶界和窄化晶界，进而有助于提高钼金属的塑性和成形性；当氧含量由2100 mg／kg降低到580 mg／kg时，钼丝的旋锻成品率提高57.2％；当铁、镍含量降低时，成品钼丝的室温延伸率提高0.51％。

Molybdenum wire(φ0.18 mm) was produced by the same pressing,sintering,rotary swaging and drawing process from molybdenum powder with different impurity elements ( Fe、Ni、C、O ) .And microscopic structure and mechanical properties of the molybdenum wire were compared.Results have shown that with the reduction of impu-rity elements, graln boundaries will be significantly purified and narrowed, then to help improve molybdenum metal plasticity and formability;When the oxygen content is reduced from 2100 mg/kg to 580 mg/kg, molybdenum wire rotary forging yield would be increased by 57 .2%.When the content of iron and nickel was reduced , the elongation of the finished molybdenum wire would be increased by 0.51%at room temperature.
