摘要：
When the Ti-6Al-4V alloy is overaged at 500-600A degrees C, nanometer-sized alpha(2) (Ti3Al) particles can be homogeneously precipitated inside a phases, thereby leading to strength improvement. Widmanstatten and equiaxed microstructures containing fine alpha(2) (Ti3Al) particles were obtained by overaging the Ti-6Al-4V alloy. Precipitation of alpha(2) (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 575A degrees 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.
