Fe-Nb-B alloys prepared by ball milling can undertake a complex microstructural evolution during milling. In order to overcome the limitations imposed by traditional X-ray bulk analysis, a comprehensive multi-technique approach was devised to systematically characterize samples with the required resolution. The combination of in-situ FIB (Focused ion beam) lift out and high resolution ATEM (Analytical transmission electron microscopy), have allowed the characterization of the phase evolution during milling. In particular, boron inclusions, not detected by X-ray diffraction, have been found to remain undissolved in the Fe matrix.
