Abstract
The development of microstructure during the aging of Ti-10V-2Fe-3Al alloy in the β and (α+β) solution-treated and quenched conditions was investigated. The results showed that the isothermal holding below 400°C yielded homogeneously distributed, spherical Ï-phase particles. Fine α aggregates are formed uniformly within β grains by nucleating at Ï particles or β/Ï interfaces. At higher temperatures, thin martensite plates decomposed in water-quenched condition. The formation of Ï phase was avoided and coarse α-phase plates directly precipitated from the β matrix. The highest hardness values were found when the alloys were aged at 400°C for 8 h. The significance of the observations was discussed in terms of the effect of aging on the precipitations and property.
