Abstract
The effects of heat treatment on microstructure and tensile properties of Ti60 alloy were investigated by optical microscope and transmission electron microscopy (TEM) as well as tensile testing. The results show that a large amount of dislocations are piled up at the grain boundaries, and no precipitations are observed after the alloy is treated at 1015°C for 2 h. Aging of the specimens at 700°C for 2 h results in the precipitation of silicides at grain and α/β phase boundaries. Extending the aging time to 24 h, excepting the silicides in the primary α and lamellar α phase, the α2 phase presents in the alloy. Extend the aging, the strength of the Ti60 alloy increases but the ductility of the alloy decreases strongly.
