Hydrogen Permeation of Ni-Nb-Zr Metallic Glasses in a Supercooled Liquid State
In this study, the hydrogen permeation in the supercooled liquid state for Ni65Nb25Zr10, Ni60Nb20Zr20 and Ni55Nb15Zr30 metallic glasses was investigated in conjunction with the discussion on the effect of hydrogen diffusion on hydrogen permeation. The hydrogen permeation of the Ni65Nb25Zr10 and Ni60Nb20Zr20 metallic glasses increases significantly by the transition from the glassy solid state t...
متن کاملOXYGEN DISTRIBUTION IN Zr-BASED METALLIC GLASSES
This paper reports the atom probe analysis results of the oxygen dissolved in the as-cast amorphous and crystallized Zr65Cu15Al10Pd10 and Zr65Cu17.5Ni10Al7.5 alloys. Impurity oxygen ranging from 0.1 to 1 at.% is dissolved uniformly in the as-quenched Zr65Cu15Al10Pd10 and Zr65Cu17.5Ni10Al7.5 amorphous alloys even though the oxygen is not added intentionally. When the Zr65Cu15Al10Pd10 alloy is cr...
متن کاملMechanical Behavior of Zr-Based Metallic Glasses and Their Nanocomposites
In the present chapter, results of our recent investigations on the role of gallium (Ga) on the aluminum (Al) site in Zr69.5Al7.5-xGaxCu12Ni11 metallic glass (MG) composition have been discussed. The material tailoring and cooling rate effects on the mechanical behavior of Zr-based metallic glasses and their nanocomposites have been studied. The substitution of Ga on the Al site in Zr–Al–Cu–Ni ...
متن کاملHydrogenation of Zr-based metallic glasses and quasicrystals
Zr-based metallic glasses and quasicrystals were electrochemically charged with hydrogen. Hydrogen absorption/ desorption as well as the in ̄uence of hydrogen on the formation and stability of quasicrystals were studied by means of X-ray diraction, electron microscopy, dierential scanning calorimetry (DSC) and thermal desorption analysis (TDA). In Zr69:5Cu12Ni11Al7:5 absorption kinetics and st...
متن کاملFatigue-Induced Damage in Zr-Based Bulk Metallic Glasses
In the present work, we investigate the effect of "fatigue" on the fatigue behavior and atomic structure of Zr-based BMGs. Fatigue experiments on the failed-by-fatigue samples indicate that the remnants generally have similar or longer fatigue life than the as-cast samples. Meanwhile, the pair-distribution-function (PDF) analysis of the as-cast and post-fatigue samples showed very small changes...
