摘要(Abstract)：

以Fe_(41)Co_7Cr_(15)Mo_(14)C_(15)B_6Y_2非晶合金为基体,通过掺杂Co_(65)Cr_(15)Zr_(10)W_(10)非晶合金成功获得了低热导率的Fe基大块非晶合金。利用四探针电阻率测试仪和激光闪射热导率测试仪分别测量合金的室温电阻率和25~150℃下的热导率。研究Co_(65)Cr_(15)Zr_(10)W_(10)非晶合金掺杂对电阻率和热导率的影响以及热导率随温度的变化关系。结果表明:在25~150℃范围内,Fe基大块非晶合金热导率随温度升高呈线性增加。Co_(65)Cr_(15)Zr_(10)W_(10)非晶合金的掺杂导致Fe基大块非晶合金的热导率和电阻率降低,当掺杂含量高于10 at%后,热导率趋于稳定。掺杂主要引起常温下声子热导率的变化,对电子热导率影响很小。提出了通过晶化温度Tx推算Fe基大块非晶合金常温下热导率的公式,声子热导率与Tx之间的关系符合Y=0.06756X-37.31568,总热导率与Tx之间的关系符合Y=0.06228X-30.58814。
