Growth characteristics of primary M7C3 carbide in hypereutectic Fe-Cr-C alloy

The microstructure of the hypereutectic Fe-Cr-C alloy is observed by optical microscopy (OM). The initial growth morphology, the crystallographic structure, the semi-molten morphology and the stacking faults of the primary M7C3 carbide are observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The in-suit growth process of the primary M7C3 carbide was observe...

Control of eta carbide formation in tungsten carbide powders sputter-coated with (Fe/Ni/Cr)

Composite powders of tungsten carbide with variable coating contents of Fe/Ni/Cr based alloys (1–15 wt.%) were prepared by sputtering. The coated powders have revealed a good performance to shape-forming and sintering. However, the presence of nanocrystalline coatings could enhance the formation of a brittle phase during sintering, named g-phase, (M,W)6C. To investigate this effect, the powders...

Evolution of magnetization reversal mechanism in Fe-Cr alloy films

A large thin film sample of FexCr1−x alloy with a composition gradient x=0.38−0.52 has been prepared by co-sputtering to investigate magnetic anisotropy and magnetization effects on reversal mechanisms. The single-phased Fe-Cr films have a bcc structure with 110 preferred orientation. Since the magnetization decreases as the Fe content is decreased and the uniaxial anisotropy energy keeps at al...
