直流磁场作用下液态铝合金热电势的变化
DOI: 10.3724/SP.J.1037.2013.00231, PP. 1069-1074
Keywords: 直流磁场,热电势,液态铝合金
Abstract:
研究了在不同温度下,直流磁场对铝合金热电势的影响.结果显示当施加在样品两端的磁场强度相差较大时,Al－2.89%Fe合金熔体的热电势逐渐降低.撤除磁场作用后,降低的热电势需要经一段时间,才能缓慢恢复到施加磁场前的初始值.这种现象,在不同温度、不同成分的铝合金熔体(包括纯Al)中被普遍观察到.样品两端磁感应强度平方差越大,热电势变化量越大;在近似均匀磁场作用下,液态铝合金的热电势没有发生变化.根据弱局域化理论,磁场使电子在传输过程中产生附加相位,改变了体系中扩展态电子的分布,从而导致合金熔体的热电势发生变化.
