Results of the57Fe Mossbauer spectroscopy of greigite from the “greigite-rich” horizon of the middle part of the miocene series (Sokolov Basin, North Bohemia) are reported. From the room-temperature transmission spectra of the powdered samples ma

The effect of creep annealing on the57Fe enriched Co-rich low magnetostriction amorphous alloys will be reported. Contrary to the Fe-B-base alloys, after creep annealing of the57Fe5Co57Ni10Si11B17 the ribbon axis becomes the hard direction. Both Moss

In contrast to the common Fe-B-base amorphous alloys, Mossbauer transmission and CEMS studies of the early stages of the nanocrystalline structure formation in the new magnetically soft FeCuNbSiB alloys produced via the amorphous way, revealed that t

Fe-Tm-B base (TM=transition metal) amorphous alloys (metallic glasses) are thermodynamically metastable. This limits their use as otherwise favourable materials, e.g. magnetically soft, corrosion resistant and mechanically firm. By analogy of the mec

57Fe backscattering Mossbauer phase analysis of the ASTM A295-70 type chromium bearing steel gas was performed for samples with varying phase composition achieved by gas carburization up to 3 wt% C followed by standard hardening, i.e. austenitizing a

Using a new design of helium-methane gas-flow detector of conversion electrons for Mossbauer spectroscopy, non-uniform nucleation of the primary α-Fe-Co phase on both contact and free surfaces of the Ar(+H2) annealed amorphous Fe75Co9B16 alloy was o
