Abstract:The microstructure and mechanical properties after different annealing treatments of Ti600 alloys were researched. The results show that Ti600 alloy has a good thermal stability, and the lamellar structure can provide good matching of strength and plasticity to get the better creep resistance; when anneal temperature increases, the strength of Ti600 alloy increases, and the strength after duplex-annealing is higher than that after conventional annealing.
Key words: Ti600 high temperature titanium alloy; microstructure; mechanical property
