Abstract
When the Ti-6Al-4V alloy is overaged at 500-600°C, nanometer-sized α2 (Ti3Al) particles can be homogeneously precipitated inside a phases, thereby leading to strength improvement. Widmanstätten and equiaxed microstructures containing fine α2 (Ti3Al) particles were obtained by overaging the Ti-6Al-4V alloy. Precipitation of α2 (Ti3Al) particles was monitored using thermoelectric power measurements for different aging conditions in the Ti-6Al-4V alloy. Overaging heat treatments were conducted at 515, 545 and 575°C for different aging times. In addition, overaging samples were examined by optical microscopy, scanning electron microscopy and hardness measurements. It was found that the thermoelectric power is very sensitive to the aging process in the two studied Ti-6Al-4V structures.
