摘要
采用熔炼、铸锭和冷热加工工艺制备了稀土微合金化铜导线,研究了La、Y、Te、Zr、Ag元素的微合金化对铜导线力学性能、电学性能和显微组织的影响。结果显示,微合金化铜导线在屈服强度为220~260 MPa条件下伸长率达到30%,电阻率为0.01715Ω·mm^(2)/m,性能优良,能满足变压器用铜导线服役要求。
The rare earth microalloyed copper wires were prepared by smelting,ingot casting and cold and hot processing,and the effects of La,Y,Te,Zr and Ag microalloying on the mechanical properties,electrical properties and microstructure of copper wires were studied.The results show that the elongation of the microalloyed copper wires reaches 30%and the resistivity is 0.01715Ω·mm2/m under the condition of 220~260 MPa yield strength.The rare earth microalloyed copper wires have excellent performance,meeting the service requirements of copper wires for transformers.
