Thermal stability and phase transformations of martensitic Ti–Nb alloys
Aiming at understanding the governing microstructural phenomena during heat treatments of Ni-free Ti-based shape memory materials for biomedical applications, a series of Ti-Nb alloys with Nb concentrations up to 29 wt% was produced by cold-crucible casting, followed by homogenization treatment and water quenching. Despite the large amount of literature available concerning the thermal stabilit...
متن کاملHydrogen evolution from Zr-based amorphous and quasicrystalline alloys
The combination of local tetrahedral order and favorable chemical composition makes amorphous and quasicrystalline Zr–Cu–Ni–Al alloys good candidates for hydrogen storage applications. Hydrogen evolution from these alloys has been studied by means of thermal desorption spectroscopy (TDS). The characteristics of hydrogen desorption from an initially quasicrystalline phase are analyzed in detail ...
متن کاملHydrogen diffusion in Zr-Pd amorphous alloys
Nuclear Magnetic Relaxation measurements of the dipolar relaxation rate due to hydrogen diffusion in Zr-Pd amorphous alloy~ have been conducted and the results interpreted in terms of the random alloy model. It is found that even though the measured activation
متن کاملAn Overview of Hydrogen Interaction with Amorphous Alloys
Theories, experimental results and applications associated with hydrogen behavior in amorphous metals and alloys are reviewed. An emphasis is made on the potential use of these advanced materials for hydrogen storage technology. Therefore, several properties that are especially relevant for such applications are assessed. These include structural models for hydrogen occupancy, sorption characte...
متن کاملExcessively High Vapor Pressure of Al-Based Amorphous Alloys
Aluminum-based amorphous alloys exhibited an abnormally high vapor pressure at their approximate glass transition temperatures. The vapor pressure was confirmed by the formation of Al nanocrystallites from condensation, which was attributed to weight loss of the amorphous alloys. The amount of weight loss varied with the amorphous alloy compositions and was inversely proportional to their glass...
