Atomic mobilities and diffusivities in fcc Co–X (X = Mn, Pt and Re) alloys
Source abstract
Abstract
Abstract The atomic mobilities of Co, Mn, Pt and Re in face-centered cubic (fcc) Co–X ( X = Mn, Pt and Re) alloys have been assessed as a function of temperature and composition by CALculation of PHAse Diagram (CALPHAD) approach. To validate the literature data and provide new experimental data, we prepared two fcc Co–Mn diffusion couples, which were used to determine the composition-dependent inter-diffusivities at 1073 and 1273 K. Based on various kinds of experimental diffusivities available in the literature and the experimental results in this work, the atomic mobilities in fcc Co–X (X = Mn, Pt and Re) alloys were obtained. Comprehensive comparisons between the calculated and measured diffusivities show that most of the experimental data can be well reproduced by the presently obtained atomic mobilities.
