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.

Reduced glass transition temperature and glass forming ability of bulk glass forming alloys

Journal of Non-Crystalline Solids, 2000
Abstract Onset temperature (solidus) T m and offset temperature (liquidus) T l of melting of a series of bulk glass forming alloys based on Zr, La, Mg, Pd and rare-earth elements have been measured by studying systematically the melting behaviour of these alloys using DTA or DSC. Bulk metallic glass formation has been found to be most effective

Glass-forming ability of butanediol isomers

Journal of Thermal Analysis and Calorimetry, 2010
In this study, the thermal behavior of butanediol isomers is investigated for temperatures ranging from 103 to 303 K using differential scanning calorimetry, complemented, when necessary, by polarized light thermal microscopy. The butanediol isomers display quite different thermal behaviors: for 1,2- and 1,3-isomers, glass transition is the only ...

Alloys of high glass-forming ability

Journal of Non-Crystalline Solids, 1996
Abstract A series of Zr-Ti-Al-Cu-Ni alloys, e.g., Zr 57 Ti 5 Al 10 Cu 20 Ni 8 , were found to have high glass-forming ability (GFA). Cylindrical bulk amorphous samples with diameters of 10 mm were produced by casting the melts in a copper mould. The Zr 65 Cu 17.5 Ni 10 Al 7.5 alloy, which was reported to have the highest GFA heretofore, was found to

Glass Forming Ability of Ca-Based Bulk Metallic Glasses

Solid State Phenomena, 2011
Knowledge of glass forming ability (GFA) of amorphous metallic alloys is very important from both theoretical and practical point of view. Thermodynamically, the Gibbs free energy difference, ΔG between the undercooled liquid and the corresponding crystalline state is driving force for crystallization. As a consequence, it is a good indicator for glass

Glass-forming ability of rare earths in fluorozirconate glasses

Journal of Non-Crystalline Solids, 1994
Abstract The effects of rare earth elements on glass formation regions in the systems ZrF 4 BaF 2 LnF 3 AlF 3 (Ln is a rare earth element and AlF 3 concentration is 4 mol%) has been examined. It is found that glass formation regions gradually shift to higher concentrations of rare earth fluoride with decreasing rare earth element radius.

U-based metallic glasses with superior glass forming ability

Journal of Nuclear Materials, 2018
Abstract By using Al as the third and B as the fourth but minor alloying elements for the U66.7Co33.3 basic metallic glass, a series of U-Co-Al(-B) alloys were designed. The quaternary U-Co-Al-B alloys exhibit significantly improved glass-forming ability (GFA) than previously reported U-based metallic glasses.

Glass forming ability and thermal stability of oxyfluoride glasses

Journal of Thermal Analysis and Calorimetry, 2009
New oxyfluoride glasses based on the system ZrO2-Pr2O3-ZrF4-BaF2 were obtained, and the glass forming ability of this system was evaluated. The effects of glass composition on both thermal stability and the crystalline phases formed upon heat treatment were determined by the DSC and XRD methods, respectively.
