It is well known that the apparent concentration of a solute element in metal, detected by atom probe tomography analysis, depends on the measurement condition such as specimen temperature, pulse fraction, and pulse frequency. The dependence was qualitatively interpreted to be caused by preferential evaporation and retention in field evaporation. A quantitative physical model accounting for the preferential evaporation and retention was proposed herein for the first time. The proposed model was… CONTINUE READING
