Abstract

We studied the elastic properties of lotus-type porous iron experimentally and theoretically. First we determined the elastic constants of lotus iron fabricated by the continuous zone-melting method by using the acoustic resonance techniques. All the elastic moduli are found to follow the well-known power-law formula. Next, we extended the effective-mean-field (EMF) theory so as to consider effects of the pore orientation on the effective elastic constants, The model calculations proved that the extended EMF theory is capable of calculating satisfactorily the elastic properties of lotus metals.
