Abstract

We have utilized X-ray absorption fine structure spectroscopy (XAFS) and "zero-field" nuclear magnetic resonance (NMR) in the investigation of the local structure and magnetic properties of Fe in nanostructured M50 type steel. Our NMR results on the assynthesized M50 type steel powders indicate that this material has a highly disordered phase(s) and some α-Fe. The NMR measurements further reveal that the particles are ferromagnetic in nature. XAFS measurements show that the as-synthesized powder sample lacks long-range crystalline order and that the immediate near neighbor shells around Fe are not like bcc or fcc Fe. On the other hand, XAFS experiments on the consolidated samples clearly show that Fe in the sample is predominantly in the form of α-Fe with good long range crystalline order.
