Synthesis, characterization and stability of amorphous alloys

Abstract

In this paper the results of chemical and electrochemical synthesis of Fe-P, Fe-W and Fe-Ni amorphous powders, investigations of their structural characteristics, stability and processes of their relaxation and stabilization during heating in the temperature range of 20-1000oC are presented.

Crystallization Kinetics of Metallic Glasses

“…Eutectic crystallization is simultaneous crystallization of two crystalline phases by a discontinuous reaction. This reaction takes longer than polymorphous crystallization to proceed because the two components have to separate by diffusion into two separate phases within the crystallized region (Minic, 2006).…”

Structural transformations of Fe81B13Si4C2 amorphous alloy induced by heating

“…Amorphous alloys are materials obtained by rapid quenching of the melt at a cooling rate of about 10 5 -10 6 K s À 1 in conditions where crystallization is suppressed [1]. The soft magnetic amorphous alloys are based on the ferromagnetic elements Fe, Co and Ni, containing the glass forming elements Si, B, C and P. The most stable amorphous alloys contain about 80 at% of transition metals (ferromagnetic component) and about 20 at% of metalloid elements (glass forming component) [2].…”
