Tracer diffusion mechanism via microscopic bubbles in Co-b-amorphous alloy

In our previous work on microscopic bubbles in AMAs, we determined the diffusion coefficients of tracer atoms via microscopic bubbles in Fe80B20 AMAs. Generally, our results were consistent with experimental data. However, the dependence of the microscopic bubbles and the diffusion coefficients on atom concentration in the AMAs has not yet been determined. Therefore, the goal of this paper is to investigate the dependence of microscopic bubbles and the diffusion coefficient of tracer atoms on B concentration in Co-B AMAs. |
