摘要
采用真空感应熔炼法制备CuCr25(W),与Cr25(C)合金,研究不同合金元素W,C对CuCr触头微观组织的影响。研究结果表明,W和C能够显著细化Cr相晶粒,W对Cr相晶粒还有球化作用,同时对Cr相进行了强化。使合金整体性能得到提高,其中耐电压强度得到显著提高。
The preparation of CuCr25(C) and CuCr25(W) alloys by vacuum inducing melting is presented in this paper. The influence of different alloy elements(C&W) on Cr-crystalline grain is studied. And the sequent effects on the physical properties and breakdown voltage are also discussed. It is found that the mechanical strength and the voltage withstanding stress have been improved for the alloys with adding of C or W.
