    Abstract:

    Texture was examed using XRD and low cycle fatigue property was analyzed using fatigue tester(25 kN) of MTS809A/T-type for Zr-4 alloy plate at room temperature in rolling direction and transverse direction, respectively, in this paper. Results show that the Zr-4 alloy plate has the obvious texture, and the low cycle fatigue property is better in rolling direction than in transverse direction. During the cycle deformation, only partial grains exhibited plastic deformation, where many dislocations and slip lines existed. The dislocations and slip lines in the deformed gains are denser in transverse direction than that in the rolling direction. The difference of low cycle fatigue lifes for the two samples is due to the texture in the Zr-4 alloy plate.
