The Effect of Carbon on the Curie Temperature of κ Phase


Article Preview

The effect of composition on the Curie temperature of κ phase Fe3AlCx was investigated by thermomagnetometry analysis (TMA). Results reveal that increasing carbon content decreases the Curie temperature. Serrations in the magnetization vs. temperature curve in the Fe3AlCx found at about 100°C, may arise from the fluctuation of carbon atoms between Site I and II of κ phase unit cell.
