Structural relaxation and its influence on the elastic properties and notch toughness of Mg–Zn–Ca bulk metallic glass

Effects of annealing on the microstructure, corrosion resistance, and mechanical properties of RE65Co25Al10 (RE=Ce, La, Pr, Sm, and Gd) bulk metallic glasses

“…for the d m values with increasing the annealing temperature to 484 K, presenting that the generation speed of free volume is faster than the annihilation, which results in the presence of the additional free volume. Similar experimental phenomena have also been reported [21,22]. Zhao et al [21] have found that the correlation between the enthalpy change and free volume showed a linear dependence for the as-annealed Mg-based BMGs over a wide temperature range.…”

“…Similar experimental phenomena have also been reported [21,22]. Zhao et al [21] have found that the correlation between the enthalpy change and free volume showed a linear dependence for the as-annealed Mg-based BMGs over a wide temperature range. Moreover, a high density of free volumes was introduced for the Zr-based BMGs annealed in the supercooled liquid region [22].…”

Corrosion of Biocompatible Mg66+xZn30-xCa4 (x=0.2) Bulk Metallic Glasses

“…One ml of the released h 2 is stoichiometrically equivalent to 1 mg of magnesium dissolved, and therefore the measurement of hydrogen evolution corresponds to indirect measurement of biodegradability and corrosion effects within the magnesium alloy. Evolved hydrogen is derived mainly from the local corroding area, what means, that the rate of hydrogen evolution is able to reliably reflect the local degradation rate of magnesium alloys [14,15].…”

Mg-based bulk metallic glasses for biodegradable implant materials: A review on glass forming ability, mechanical properties, and biocompatibility

“…Induction furnace heating process which has its source of heating from an alternating current solenoid coil was used by many researchers to fabricate Mg-based BMGs under fully argon atmosphere to obtain different metallic glass diameters [14,22,29,33]. A study reported a fully developed amorphous ribbon of Mg-based BMG fabricated using an induction furnace under partial argon atmosphere and a single roller melt-spinning technique in a partial helium atmosphere [28].…”
