Phase Evolution and Spinodal Decomposition in Ti-13Mo-2Fe During Aging
摘要
This paper investigates the phase formation in Ti-13Mo-2Fe (wt pct) during aging. Ti-13Mo-2Fe prevented athermal ω formation after solution treatment. However, the high diffusivity of Fe favored isothermal ω formation and growth during aging. Furthermore, a secondary BCC phase was detected in the aged sample. The isothermal ω generates Mo- and Fe-enriched regions that may drive the spinodal decomposition of the parent β at 400 °C. The simulation showed a good agreement with the experimental data.
