The textured shape memory alloys exhibits anisotropic because the property of single crystal is strongly orientation dependent. The effect of texture on phase transformation strain in CuZnAl shape memory sheets was investigated. The texture of parent austenite was measured by X ray goniometer and analyzed by the orientation distribution function. Subsequently, using the texture parameters and single crystal properties, the phase transformation strains at the different directions of rolling plane by the statistically averaging method were calculated. It was showed that the experimental results are agreeable with the calculated ones. It is well explained that this anisotropy of phase transformation strain is mainly caused by the crystallographic texture of the rolled sheets.
