Layered systems, obtained by e-beam irradiation of molybdenum sheets mechanically clamped to ARMCO iron, plain carbon steel and high alloy austenitic steel substrates, have been analysed by means of conversion X-ray Mössbauer scattering and X-ray diffraction. When the substrate is iron or carbon steel, the structure of the surface layer is completely ferritic with a certain amount of iron-atoms coordinated with molybdenum atoms. If the substrate is fully austenitic, the e-beam treated surface structure presents a broad ferritic-martensitic component. The influence of the cooling rate of the e-beam molten layer is also discussed in relation to the observed surface structures.
