title = "The diffusivity and solubility of copper in ferromagnetic iron at lower temperatures studied by atom probe tomography",
abstract = "The diffusion coefficient and the solubility limit of copper in ferromagnetic iron were directly measured using atom probe tomography at lower temperatures than in previous studies. Cu-Fe diffusion couples were annealed at temperatures from 550 to 750 °C. The diffusion coefficient was determined to be D = 0.48 exp(-Q/kBT) m s-1 (Q = 3.22 eV), which, below 650 °C, is about 1.3 times higher than the extrapolation from a previous study considering the magnetic effect. The measured Cu solubility limit is in good agreement with literature.",
