摘要 Ni72-xSi15B13+x(x=0,2,4,6,8)非晶合金电阻温度特性曲线表明它们在高于室温时电阻随温度呈线性变化,其室温电阻串ρ0和电阻率温度系数Cf与合金总传导电子浓度Ce有关.采用Nagel推广的液态金属Ziman理论对此作出了较好的解释.当与其它Ni基非晶合金的实验结果比较时,发现可以根据TM—M非晶合金总传导电子浓度Ce。 y measuring the temperature dependances of resistance of amorphous Ni72-xSi15B13+x(x=0,2,4,6,8) alloys, it has been found that there is a linear relationship of the resistance with temperature above room-temperature, and the room temperature resistivity ρo and temperature coefficient of resistivity Cf are related to the total concentration of effective conducting electrons Ce. For the results, using the Ziman theory of liquid metal extended by Nagel, a reasonable explanation has been made. Comparing with experimental results of other amorphous Ni-based alloys, the results show that: for amorphous TM-M alloys, by calculating their Ce values, some amorphous alloys with different values of po and Cf may be prepared as predicted.
