Formation of ethylene-vinyl acetate composites filled with Al–Cu–Fe and Al–Cu–Cr quasicrystallline particles

Journal of Materials Research and Technology, 2019
Icosahedral Al65Cu23Fe12 and decagonal Al73Cu11Cr16 quasicrystalline powders were synthesized by the mechanical alloying and subsequent annealing. Morphology evolution at mechanical alloying of Al-based powders was found to be determined by competition ...

Formation mechanism of amorphous alloys by mechanical alloying.

DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1991
As a technique in synthesizing an amorphous solid, attention has been directed to the solid state reaction. Here a rapid quenching is no longer required and, instead, a very slow reaction takes place in the course of amorphization. This assures us to provide a unique opportunity in studying how any crystals like fcc and bcc transform into an amorphous ...

Effect of intercritical processing temperature on mechanical properties, microstructure and microhardness of ferrite - bainite medium carbon dual phase steels

Cogent Engineering, 2021
This research focusses on the dual phase (ferrite and bainite) treatment for medium carbon steels containing same carbon content (different alloying elements) and mechanical properties, as well as microhardness and microstructure. Dual phase treatment is
