The phonon density of states of {γ}-Fe precipitates in a Cu matrix were studied as a function of particle size by using nuclear resonant inelastic scattering of synchrotron radiation. The host metal affects the phonon density of states of the precipitates up to 30 nm in diameter. Larger precipitates are free from the influence of the host metal and show rather similar phonon density of states to those of fcc-Fe alloy bulk specimens such as stainless steel (310ss) and Fe₇₀Ni₃₀ at room temperature although {γ}-Fe is unstable at room temperature under an atmospheric condition. Careful observation, however, yields characteristics of {γ}-Fe precipitates in the phonon density of states.
