Effect of iron content on β → α phase transformation behavior of Ti-5Al-xFe (x = 1, 2.5, 4) alloys during continuous cooling

Journal of Materials Research and Technology, 2019
We investigated the effect of Fe content on the β → α phase transformation behavior of Ti-5Al-xFe (x = 1, 2.5, 4) alloys during continuous cooling. The presence of Fe delayed long-range diffusional phase transformation, thus facilitating diffusionless ...
