Understanding the Origin of Glass Forming Ability in Metallic Glasses [PDF]

open access: yes, 2018
The glass forming ability of metallic glasses has been one of their most studied yet least understood properties. Crystal nucleation in a recently development Ni-based metallic glass was studied by undercooling in a DSC under a variety of conditions and showed stochastic very deep undercooling behavior.

Critical evaluation of glass forming ability criteria

open access: yesMaterials Science and Technology, 2016
The available glass forming ability criteria have been examined by classifying them into four basic categories depending on critical temperatures, thermodynamic quantities, topological and kinetic aspects of glass forming alloys.

Effect of W addition on the glass forming ability and mechanical properties of Fe-based metallic glass

open access: yesJournal of Alloys and Compounds, 2018
The effects of refractory element W addition on the glass forming ability (GFA) and mechanical properties of Fe47-xCr20Mo10WxC15B6Y2 (x = 0, 2, 4, 6 at. %) alloys were investigated. The supercooled liquid region Delta T-x (T-x-T-g) and criterion gamma [T-

Glass forming ability of bulk glass forming alloys

Scripta Materialia, 1997
In general, rapid quenching from the melt at cooling rates in the range of 10{sup 4} to 10{sup 6} K/s is required to obtain glass formation in metallic alloys. However, recent development have shown that bulk glass formation at cooling rates as low as {approximately}1 K/s can also be obtained in Zr, Mg, La, Nd, Ti, Cu and Fe based metallic alloy ...

Glass-forming ability of alloys

Journal of Non-Crystalline Solids, 1993
Abstract New amorphous alloys exhibiting a wide supercooled liquid region before crystallization were found to form by melt spinning in wide composition ranges of LaAlM, MgYM and ZrAlM (M = Ni or Cu) systems consisting of the constituent elements with significantly different atomic sizes.

Early drug development predictions of glass-forming ability and physical stability of drugs

open access: yesEuropean Journal of Pharmaceutical Sciences, 2013
The purpose of this study was to investigate if rapidly measured physical properties can predict glass-forming ability and glass stability of drug compounds.
