The Young`s modulus of cementite, Fe{sub 3}C, is one of the physical quantities which are inevitably required to understand the mechanical properties of the high strength steels. Thus, efforts have been devoted to estimate the Young`s modulus of cementite from the mechanical tests on cast iron containing cementite. Very recently, the electron-shower-assisted physical vapor deposition (ES-PVD, hereafter) has been applied to prepare single phase cementite films, and their Young`s modulus and Poisson`s ratio have been evaluated using the surface wave method. On the other hand, the vibrating reed method to measure the Young`s modulus of a thin film deposited on a reed-substrate has been established recently. In the present paper, the authors applied the vibrating reed method to the single phase cementite films deposited on silicon reed-substrates to determine the Young`s modulus of cementite.
