to increase the glass forming ability and thus the thermal stability of the glass. Indeed, the addition of yttrium (alloy composition investigated: Mg80Cu10Y10) resulted in a shift of the crystallization onset to higher temperatures and furthermore the amorphous alloy showed a clear glass transition followed by a temperature range in which the

Role of Nanocrystallites of Al-Based Glasses and H2O2 in

Dec 24, 2020 of Al-based glasses is improved and the Y6 ribbon has formed nano-scale crystallites embedded in the amorphous matrix and it has the largest improvement in MO solution degradation. These results indicate that forming nano-scale crystallites and adding H2O2 are effective methods to improve the degradation ability of Al-based glasses in azo dye

relatively low glass-forming ability [Inoue 1998]. In general, Al-based metallic glasses can only be obtained by melt-spinning in the shape of ribbons or by gas atomization in form of powder [Inoue 1998]. Only very recently, a single-phase amorphous Al-based alloy with 1 mm diameter has been successfully produced by solidification methods for the

Crystallization Kinetics Study in Al Ni La Amorphous Alloy

Among the various amorphous Al alloy systems, Al Ni RE (La, Y, Ce) amorphous alloys have Corresponding author: E-mail address: [email protected] been studied intensively because of their excellent glass-forming ability (GFA) and high thermal stability [12-15]. It has been reported that the glass formation is favored in

The higher the number of elements in a system, the higher is GFA. 2. GFA is also high due to a negative mixing enthalpy of the components in a system. 3.

This paper is focused on preparation and description of rapidly solidified Al-Cr-Fe-Ti alloy by melt spinning. The effect of Ce addition on material stabilization was also observed. It is supposed that alloying of Al-TM alloys by rare earth metal can increase amount of metastable phases and stabilize them at elevated temperatures.
