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 and 34 h) and Al 40 Cu 10 Mn 25 Ge 25 (MA for 42 h).
Figure 1. XRD spectra of the TiFe IMC alloy in the as-cast and...
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...
Ti-Fe Phase Evolution and Equilibria Toward β-Ti Superalloys
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 phase and the α-Ti phase. A representative XRD spectrum for the alloy aged at 650 °C for 100 h is shown in Fig. 5(b).
