Electrical resistivity of the nanocomposites Sn_96.5Ag₃Cu_0.5 and Sn_95,5Ag_3,8Cu_0,7 lead-free solder alloys with minor admixtures of carbon nanospheres (0.05 wt%) was measured in a wide temperature range, including a melting-solidification region. Influence of the carbon nanospheres content on electrical resistivity values has been analyzed. Carbon nanospheres were obtained by electrical discharge method from diesel fuel, cyclohexane, and aviation kerosene. The matrix samples were produced by planar flow casting technique in the form of thin ribbons. Electrical resistivity measurements were performed using four-probe method. Hysteresis between the heating and cooling electrical resistivity curves relates to the non-equilibrium solidification.

在较宽的温度范围内测量了含有少量碳纳米球 (0.05 wt%) 的纳米复合材料 Sn _96.5 Ag ₃ Cu _0.5和 Sn _95,5 Ag _3,8 Cu _0,7无铅焊料合金的电阻率，包括熔化-凝固区域。分析了碳纳米球含量对电阻率值的影响。采用放电法从柴油、环己烷和航空煤油中获得碳纳米球。基体样品是通过平面流铸技术以薄带的形式生产的。使用四探针法进行电阻率测量。加热和冷却电阻率曲线之间的滞后与非平衡凝固有关。
