航天发动机液氢管路用CT20钛合金管材冷弯成型过程复杂，实际弯曲中发现原始管材的表面和显微组织对其影响较大。采用数控弯管机对不同原始状态管材进行冷弯，采用扫描电镜和光学显微镜等观察组织和断口，分析弯管断裂及表面缺陷的产生原因。

The cold bending process of CT20 titanium alloy tubes used for spaceflight engine tube to carry liquid hydrogen is complex. Numerical control bending tube machine was used to bend the tubes of different original conditions, and the reason for rupture and surface defect of the bending tubes was studied by SEM and TEM. The results show that surface processing has a limited influence on tubes bending, and tubes with isometric microstructure can be bended while those with lath microstructure cannot be bended. The bending tubes with good quality can be processed by adjusting the die and parameter of numerical control bending tube machine.
