Oxidation of Zr-based metallic glasses in air

Effects of environment on the sliding tribological behaviors of Zr-based bulk metallic glass

“…Thus, both oxidation and crystallization could take place during the sliding process due to the sufficiently high flash temperature. Triwikantoro et al [30] analyzed the oxidation behavior in a series of Zr-based metallic glasses and found that the oxide scales formed during oxidation have a nanocrystalline microstructure consisting mainly of tetragonal ZrO 2 and monoclinic ZrO 2 . Likewise, a lamellar structure consisting of tetragonal ZrO 2 , embedded in a nanocrystalline solid solution, was found after oxidation of Zr-based metallic glasses [31].…”

Diffusion mechanism of Zr-based metallic glass during oxidation under dry air

“…Köster et al [7,8] studied the oxidation behaviour of various Zr-based metallic glasses. Contrary to the observation of Sun et al, no Zr-depleted or other metal-rich zone was observed in the interface between the oxide scale and the substrate alloy matrix.…”

Oxidation Resistance of Nanocrystalline Alloys

“…Improved oxidation resistance of FeBSi [87], Ni-based alloys [88][89][90][91][92][93], Zr and its alloys [40][41][42][43], Cr-33Nb [94], Fe-Co based alloys [95,96] and Cu-Ni-Cr alloys [97] is reported in their nanocrystalline form (in comparison to their microcrystalline counterparts). The mechanistic role of a nanocrystalline structure leading to the improved oxidation resistance is discussed below:…”

“…However, the effect of the nanocrystalline structure on the hightemperature oxidation resistance has attracted only a limited research attention. Oxidation resistance of nanocrystalline Ni-Cr-Al [34][35][36], Fe-Cr [37][38][39], and Zr [40][41][42][43] based alloys have been mainly investigated and in most of the cases, oxidation resistance has been reported to improve due to nanocrystalline structure.…”
