1995年11月1日 · Mechanical alloying (MA) technique has been used to synthesize metastable alloys with nominal compositions Ti 2 Fe (MA for 1, 5, and 26 h), Al 65 Cu 20 Fe 15 (MA for 26 …

In this paper, we report the first hydrogenation (activation) of a 1.2Ti-0.8Fe alloy synthesized by induction melting (9 kg ingot). The alloy presented a three-phase structure composed of a main...

2023年12月10日 · The spectral profiles of the alloys step-quenched and aged at 650 °C for time periods between 2 and 500 h contain peaks consistently attributable to the β-phase, β′-TiFe …

According to the XRD data in Fig. 2 (a), after 10 min of the MA treatment there are two separate phases of Fe and Ti which yet do not react with each other. The estimated layer thickness is …

The Ti2FeHx and FCC are the stable hydrides formed by the secondary Ti2Fe and BCC phases, respectively. The stoichiometry of the Ti2FeHx was calculated to be between x = 3.2–4.75.

The evolution of the phase composition and microstructure of the alloys with the milling time was studied using X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM). The …
