Abstract

Elastic constant of functionally gradient materials (FGM) is one of the most important material properties. The authors have developed new measurement procedures for local elastic constants for some uniform industrial materials by using a LFB acoustic microscope. The purpose of this paper is to verify the versatility of the LFB acoustic microscope in the measurement of the elastic constant distribution of FGM. Partially stabilized zirconia/stainless steel FGM specimens from four various fabrication routes were used for the measurement by the LFB acoustic microscope to estimate the elastic constant distribution in the graded samples. It has been shown that the present method is sufficiently applicable to the accurate determination of the local elastic constant in FGM.
