Abstract
We determined the isotropic indentation modulus of precipitates in cubic materials by using the indentation modulus of the matrix as a reference. This eliminates major practical difficulty of repeatedly switching between a sample and a reference for measurement of indentation modulus using atomic force acoustic microscopy. The methodology has been demonstrated for mapping the elastic stiffness of ~500 nm sized M23C6 precipitates in alloy 625 and ferritic steel with a spatial resolution of ~50 nm.
