摘要：
In order to determine the elastic stiffness of Zr-2.5Nb CANDU pressure tube materials, the resonance frequencies of a rectangular parallelepiped specimen were measured and compared with the calculated resonance frequencies based on the input data of estimated stiffness of a polycrystalline Zr-2.5Nb specimen, dimensions and density. The estimated elastic stiffness was determined using its orientation distribution function measured by x-ray diffraction and the reported elastic stiffness of a zirconium single crystal. Through comparison of calculated frequencies with that measured by resonance ultrasound spectroscopy, accurate elastic stiffness has been determined by iteration and convergence processes.
