| Abstract(in English) | In order to calibrate a fine-focus-beam acoustic microscopy system,it is necessary to introduce a standard specimen whose bulk acoustic properties,viz.,the independent elastic constants and density,are measured with high accuracy.For this purpose,we have developed a method of determining elastic constants of isotropic specimens by the bulk ultrasonic wave pulse interference method. Single crystals are more desirable for a standard specimen at higher frequencies because of their high homogeneity and low attenuation.In this paper,this method is extended to anisotropic specimens.A way to determine elastic constants more precisely for nonpiezoelectric cubic single crystals is discussed in measuring longitudinal and shear wave velocities for(100),(110),and(111) specimens.Elastic constants of Gadolinium Gallium Garnet,Si,and Ge were determined,and compared with the published data. |
