Effect of silver on the glass forming ability of MgCuGdY bulk metallic glasses

High glass forming ability correlated with microstructure and hydrogen storage properties of a Mg–Cu–Ag–Y glass

“…Among BMGs, magnesium-based systems are specifically interesting because of high strength, low cost and extraordinary high GFA [21][22][23]. [24], because of the large atomic size mismatch between Ag and the other constituents, the large negative heat of mixing in AgMg and Ag-Y and the significant reduction in crystal growth rate [25].…”

“…Both T rg = 0.592 and γ = 0.414 refer to an excellent glass former [23,29]. At the glass transition, the thermogram exhibits the usual endothermic event (H g ) which corresponds to a structural relaxation.…”

Mg–Ni–Gd–Ag bulk metallic glass with improved glass-forming ability and mechanical properties

“…Especially, the effect of Ag addition on the GFA of MgeCueGde(Y) alloys was studied by Soubeyrou and co-workers. The critical glassy diameter (D c ) was increased to 10 mm (Mg 65 Cu 20 Gd 10 Ag 5 , Mg 58.5 Cu 24.5 Gd 9 Y 2 Ag 6 and Mg 58.5 Cu 27.5 Gd 9 Y 2 Ag 3 ) from 7 mm (Mg 65 Cu 25 Gd 10 ) and 8 mm (Mg 58.5 Cu 30.5 Gd 9 Y 2 ) [3].…”

Enhanced UV emission of Gd3+ in glass by Ag+ co-doping

“…Er 3 þ , Eu 3 þ , Dy 3 þ , Sm 3 þ , Tb 3 þ , Nd 3 þ ) due to energy transfer processes [7][8][9][10][11][12][13]. However, investigations concerning Gd-Ag combinations have been focused in the past for purposes other than Gd 3 þ luminescence, for instance aiming for the synthesis of compounds with magnetic properties and the formation of metallic glass alloys [14,15]. In such a ground, the present work investigates for the first time on Gd 3 þ -Ag þ interactions in a phosphate glass host.…”
