    摘要:

    用多次擠壓-拉伸方法研究了Ag-Cu-C多芯復(fù)合材料的加工工藝。試驗(yàn)表明,隨著擠壓次數(shù)增加,擠壓系數(shù)升高,材料的室溫抗拉強(qiáng)度及延伸率下降,電阻率升高。用該工藝制出了橫截面含有1067857根Ag,Cu,C,其間相互隔開并呈均勻分布的纖維狀的復(fù)合絲。

    Abstract:

    The process to manufacture composite material Ag-Cu-C with multimillion-fibrous structure has been investigated by indirect reapated extrusion-drawing method. The results show that, with increasing the number of extrusion, the extrusion coefficient and specific resistance increase, but ultimate tensile strength and elongation at room temperature decrease. A composite wire, which consists of 1067857 homogeneous distributed fibres of Ag, Cu and C, arranged at intervals has been prepared.
