Assessment of atomic mobility for BCC Ti-Mn and Ti-Al-Mn alloys

The atomic mobility in BCC Ti-Mn and Ti-Al-Mn alloys was assessed by using the DICTRA software after critically evaluating all available experimental diffusion data. Good agreements were obtained from the comprehensive comparisons between the calculated and experimental diffusion coefficients. The interdiffusion behaviour was further well predicted, confirming the reliability of the present mobility parameters.
