    摘要:

    研究了Ni或Co的加入對真空感應(yīng)熔煉制備的CuCr25合金的組織形貌和物理性能的影響。結(jié)果表明：加入Ni或Co后可以明顯改善CuCr25合金的顯微組織，避免出現(xiàn)Cr的宏觀偏析，大大提高了成品率，提高了合金的耐電壓強(qiáng)度和硬度，合金的電導(dǎo)率有所降低。真空感應(yīng)熔法制備的CuCr25合金達(dá)到了常規(guī)方法制備的CuCr50的技術(shù)要求。

    Abstract:

    The effects of additive Ni and Co on the microstructures and characteristics of CuCr25 alloys prepared by vacuum induction melting have been studied. The results show that both Ni and Co eliminate Cr segregation, and significantly improve the microstructures of CuCr25 alloys. The additive Ni and Co also increase the dielectric strength of the alloys, but slightly decrease electrical conductivity. As a result, the properties of vacuum induction melted CuCr25 alloys reach the specifications of conventional CuCr50 alloy.
