Thermal stability of Fe/Mo layers

The thermal stability of an iron/molybdenum bilayer was determined using Rutherford backscattering spectrometry and X-ray diffraction. Substantial interdiffusion (3%) was observed upon annealing at 973 K for one hour. High temperature annealing of Fe/Mo layers in oxygen ambient is therefore not suitable for the formation of magnetite layers.

Calculated oscillation periods of the interlayer coupling in Fe/Cr/Fe and Fe/Mo/Fe sandwiches.

Interdiffusion of Refractory Elements in Fe-Cr-X (X-Mo, W) and Fe-Mo-W Ternary Iron Alloys

Interdiffusion coefficients of the refractory elements in Fe-Cr-X (X 1⁄4 Mo, W) and Fe-Mo-W ternary alloys were measured on the basis of the modified Boltzmann-Matano method for ternary systems. The cross interdiffusion coefficient, ~ D CrW was positive in Fe-Cr-W ternary alloy, indicating that W accelerates interdiffusion between Fe and Cr atoms. On the other hand, the cross interdiffusion coe...
