研究了TiNbTaZr合金在冷轧过程中的形变织构和应变诱发α″马氏体织构。在不改变轧制方向的情况下，通过20%和90%的压下量轧制合金。用X射线衍射方法研究了冷轧试样的织构。变形量为20%时，除{221}β <$114 <$β孪晶织构外，还出现{100}β <$001 <$β织构。在90%冷轧态下，沿轧制方向出现{100}β <$011 <$β织构，应变诱发α″马氏体织构沿着轧制方向（RD）和横向（TD）分别向[010]和[001]方向发展。超弹性应变（α SE）沿沿着RD和TD表现出较高的值。纯弹性应变（Δ NE）沿沿着RD和与RD成45°时显示出较高的值。
This work investigates the deformation texture and strain-induced α″ martensite texture of TiNbTaZr alloy during cold rolling. The alloy is rolled by 20% and 90% reductions without changing rolling direction. Textures of cold-rolled specimens are investigated by X-ray diffraction measurements. Besides {221}β〈114〉βtwinning texture, {100}β〈001〉βtexture is developed in the specimen with 20% reduction. In the 90% cold-rolled specimen, {100}β〈011〉βtexture appears along rolling direction and strain-induced α″ martensite texture tends to [010] and [001] directions along rolling direction (RD) and transverse direction (TD), respectively. Superelastic strain (ɛSE) exhibits higher value along RD and TD. Pure elastic strain (ɛE) shows higher value along RD and 45° from RD.
