The use of DSC curves and the Kronmüller theory to study the level of structural defects of Fe-based bulk amorphous alloys [PDF]

Bulletin of the Polish Academy of Sciences: Technical Sciences, 2023
This article presents the results of tests carried out on rapid quenched Fe-based alloys. The alloys were made using an injection-casting method. The actual structure of the alloys was also studied using an indirect method, based on H.

Tensile Properties of Melt-Extracted and Annealed Ni/Fe-Based Amorphous Metallic Fibers

Metals, 2022
Here, melt-extracted Ni- and Fe-based amorphous metallic fibers (AMFs) were annealed below their glass transition temperatures. The tensile behaviors and microstructures of the melt-extracted and the annealed AMF samples were studied.

General methods for free-volume theory [PDF]

The Journal of Chemical Physics, 2005
Free-volume theory for understanding depletion phenomena in mixtures of two species is generally derived using scaled-particle theory for those specific entities. Here we first give a general scaled-particle method for convex bodies in terms of the characteristic geometrical measures of the depletion agent, i.e., its volume, surface area, and ...
