Critical evaluation of glass forming ability criteria [PDF]

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. A large number of glass forming alloys of widely varying natures and origin have been analysed with their experimentally ...

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.

Influence of preparation pathway on the glass forming ability

International Journal of Pharmaceutics, 2017
The glass forming ability (GFA), i.e. the ease of amorphization of drugs, is mostly investigated using the critical cooling rate upon melt quenching to generate an amorphous product via the thermodynamic pathway. However, amorphous materials can also be prepared via the kinetic pathway by milling.
