Study on the Transformation of (α+β) Phase to β Phase in Deformed Ti-6Al-4V Alloy during the Heat Treatment

Abstract:

In the present paper the Ti-6Al-4V alloy with α and β phases was deformed by hot rolling and solution heat treated at different temperature for 30 minutes to investigate the transformation of (α+β) to β. The results show that the deformed alloy possesses the typical (α+β) dual-phases microstructure, when the alloy is treated below the 950 °C. With the increase of the heat treatment temperature the volume of α phase decreases significantly. When the temperature is higher than the 970 °C, almost no α phase is left in the alloy.
