Properties of as-cast and structurally relaxed Zr-based bulk metallic glasses

The effect of annealing on the mechanical properties of a ZrAlNiCu metallic glass

“…Annealing will result in the reduction in free volume, and is believed to be the reason for the embrittlement in Zr-based BMGs [19,20]. Recent studies [21][22][23] indicate that nanocrystals can act as an obstacle to shear bands propagation and nucleate sites for new shear bands, thus improving the plasticity of BMGs. However, using impact toughness experiments, Nagendra et al [25] observed substantial decrease of the impact toughness of a La-based metallic glass with the introduction of a small percentage of crystallinity.…”

Mechanical Properties of Bulk Metallic Glasses at Cryogenic Temperatures

“…4 actually contains a certain level of nanocrystals in the bulk metallic glass. 57 It is unclear whether or not the BMGs used for the investigation above contain nanocrystalline phases since they were generally confirmed by X-ray diffraction (using Cu Kα radiation) and differential scanning calorimetry. It is of interest to study how their mechanical properties are inflected by their structures at nanometer scale and cryogenic temperatures.…”

Electrochemical and surface investigation of zirconium based metallic glass Zr59Ti3Cu20Al10Ni8 alloy in nitric acid and sodium chloride media

“…Mechanical properties such as ductility, plasticity and fatigue behavior are comparable to that of high strength crystalline alloys which are adequate to meet the stringent manufacturing requirements for various components in reprocessing plant [20][21][22]. Main advantage with such type of material lies in that, they can be cast into different shapes and dimensions for critical applications demanding superior corrosion resistance, better resistance to cavitation corrosion, erosion and wear characteristics [23][24][25]. Nevertheless, concerns too exist regarding their thickness for large-scale industrial application.…”
