Interaction of the solute niobium or molybdenum with grain boundaries in alpha-iron
Three-dimensional atom probe (3DAP) was used to estimate solute-grain boundary interactions for Nb or Mo in alpha-Fe. By using the Langmuir-McLean isotherm, effective Gibbs free energies of segregation in alpha-Fe, DeltaG(b), at 800 degreesC were estimated to be - 38 +/- 2 U mol(-1) for Nb and - 28...
