Crystallization of Fe80P13C7 amorphous alloy powder
Journal of Materials Science Letters, 1990In this letter, we describe the crystallization process of amorphous alloy powder. The phase transition from amorphous to crystalline was observed using a differential thermal analyser (DTA) and a vibrating sample magnetometer (VSM). The crystal structure was studied by X-ray diffraction (XRD) with Mo-K radiation.

Amorphous magnetic powders — Some special peculiarities
Journal of Magnetism and Magnetic Materials, 1988Abstract The amorphous powders prepared by a high-rate borohydride reduction process propose the possibility for some principal conclusions concerning the occurence of closest packing of the monodomain magnetic globules. The simulataneous nitrogenation, pressing and determination of the thermal effects of crystallization provided for both kinds of ...

Amorphous fine-particle Ni-B powders
Inorganic Materials, 2000The chemical reduction of Ni2+ by aqueous sodium borohydride yields fine-particle Ni-B powders containing 11 to 43 at. % B, depending on solution composition and precipitation temperature. The crystallization processes induced by heating the powders depend significantly on boron content.

Study on Amorphous Silica Powder Properties
Advanced Materials Research, 2012In this paper amorphous silica powder properties are analyzed and studied. It shows that precipitated silica has larger specific surface area, higher absorption value, higher whiteness and lower bulk density. Different usage of amorphous silica has different properties and different particle size. The order of particle size is that precipitation silica

Regular Cu-based amorphous alloy powder
Journal of Alloys and Compounds, 2010Abstract The plate-like powder of Cu 60 Zr 30 Ti 10 amorphous alloy was prepared by ball milling. The amorphization and deformation mechanisms and thermodynamic properties were also investigated. The powders are milled into plate-like powders and their thicknesses decrease with increasing of milling time.
