论文摘要
我们已经使用锁定热量表研究了铁碳合金（即铸铁和钢）中异常的埃丁豪斯效应（AEE）。所有合金均表现出清晰的AEE诱导的温度调节，其异常的ettingshausen系数是在室温下大于纯铁的数量级。由于异常的Ettingshausen系数的显着增加，在延性铸铁中AEE的无量音数字是纯铁的55倍。我们的结果揭示了铁碳合金作为横向热电材料的潜力，尽管需要优化组成和微观结构。
We have investigated the anomalous Ettingshausen effect (AEE) in iron-carbon alloys, i.e., cast irons and steel, using the lock-in thermography. All the alloys exhibit the clear AEE-induced temperature modulation, and their anomalous Ettingshausen coefficient is an order of magnitude greater than that of the pure iron at room temperature. The dimensionless figure of merit for AEE in the ductile cast iron is 55 times greater than that in the pure iron owing to the significant increase of the anomalous Ettingshausen coefficient. Our result reveals a potential of iron-carbon alloys as transverse thermoelectric materials, although the composition and microstructures optimizations are necessary.
