航天發動機液氫管路用CT20鈦合金管材冷彎成型過程復雜，實際彎曲中發現原始管材的表面和顯微組織對其影響較大。采用數控彎管機對不同原始狀態管材進行冷彎，采用掃描電鏡和光學顯微鏡等觀察組織和斷口，分析彎管斷裂及表面缺陷的產生原因。

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.
