The thixoformability of Ti14 was evaluated by upsetting and die forging tests, and the microstructure and mechanical properties of the forgings were also investigated. The results show that low upsetting force and excellent upsettability with the upsetting reduction in height of 70%~85% could be obtained in semi-solid state ranging from 1000 to 1100 °C. Die forging tests also show the excellent workability with a forging ratio of 75% in the temperature range of 1000 to 1050 °C. It is found that the existence of liquid on grain boundary may serve to relax the stress concentrations caused by solid deformation, causes low deformation resistance and finally improves forgeability of the alloy. The microstructure of samples reveals that dynamic recrystallization might occur during thixoforging and the grain refinement is attained, which also benefit in the improvement of the semi-solid formability and mechanical properties of forgings
