摘 要: 研究不同锻造工艺生产的BTi62钛合金棒材对组织、性能的影响。结果表明：BTi62钛合金采用β锻造工艺和α+β两相区锻造工艺生产的棒材，均可获得良好的组织与性能，可以达到设计要求。采用β锻造工艺，由于变形抗力较小，锻造火次少，生产效率高，容易操作，建议生产时采用该工艺。

Abstract:The effects of different forging processes on microstructure and mechanical properties of BTi62 titanium alloy bars were studied. The results show that the titanium alloy BTi62 bars produced through β forging process and two phase region (α+β) forging process have good microstructure and properties which can meet the design requirements. By β forging process, the production efficiency is high and it is easy to operate due to the small resistance of deformation and less forging times. This process is proposed to be adopted.
