A complete study of Ms-30°C polycrystalline CuAlBe shape memory alloy is made by X Ray diffraction using a texture goniometer equipped with a curved position sensitive detector. Austenite and martensite unit cells parameters are measured. Measured indexes and orientation of the habit plane are compared to those expected by the lattice parameters. Austenite after extrusion shows a strong fiber texture, volumic fraction of austenite and martensite are rneasured according to the deformation. Internal deformations of three grains of a Ms-100°C CuAlBe sample are followed during their macroscopic deformation.
