Phase formation and thermal stability of amorphous ZrNbCrMo thin films

Hydrogen-Induced Enhancement of Thermal Stability in VZr(H) Metallic Glasses

“…The additional stability towards the edges of the composition range suggests that it could be possible to synthesize V x Zr 67-x H 33 alloys with V:Zr ratios that are impossible in the binary alloy. This is because the thermal stability often decreases for alloys with a composition close to the amorphous-to-crystalline boundary [18] .…”

“…UHV conditions are important when studying the thermal properties of a material: the thermal energy will eventually be comparable to the activation energy of chemical reactions, making it more likely for the ambient environment to react with the sample. For instance, the onset of oxidation can occur at elevated temperatures even when capping layers are used [18] . Protection against oxidation is especially important for Zr-containing alloys due its large affinity for oxygen.…”

“…Therefore, a wider composition range compared to a crystal is accessible in the amorphous state, making it possible to fine-tune the elemental ratios and thus influence the properties of the alloy. The chemical composition is crucial for the formation and thermal stability of metallic glasses, but the most important parameters are found empirically to be the elemental melting points [16] , atomic size mismatch [17,18] , and the liquid mixing enthalpies among the constituents [19] .…”

(Digital Presentation) Influence of Preliminary Anodization of Amorphous Alloy Co75Si15Fe5Cr4.5Al0.5 in Ionic Liquid on Corrosion Resistance

“…The absence of defects increases the mechanical strength of amorphous alloys due to the fact that it is more difficult for the molecules of the active medium to penetrate into the structure of the material and this increases the time required for destruction. Their high hardness also contributes to increased wear resistance, and increases corrosion resistance (15). Natural surface oxide on amorphous alloys is usually an oxide film that can prevent corrosion.…”

Combinatorial Design of Amorphous Tanisic Thin Films with Enhanced Hardness, Thermal Stability, and Corrosion Resistance

“…Furthermore, the high cooling rate [25] can be utilized to synthesize metallic glasses over wide composition ranges [26], whereby composition and property relationships can be determined. In this work, combinatorial design approaches and compositional tuning [27,18,6,[28][29][30] have been employed to enhance the material properties of TaNiSiC and TaNiC glasses, which to our knowledge have not been studied before. They are expected to form metallic glasses over wide composition ranges due to high cooling rates during sputtering and their spread in atomic radii (Ta: 147 pm, Ni: 127 pm, Si: 117 pm, and C: 77 pm) [32,33].…”
