The Young's moduli of the atomized cast-iron porous sintered bodies, which were made by the vacuum sintering method and the pulse electric current sintering method, were measured by the grind-sonic method. And, we discussed the relationship of the Young's modulus and the relative density of the atomized cast-iron porous sintered body taking into account of the microstructure. The results were as follows:<BR>(1) The Young's modulus of the vacuum sintered body was governed by the porosity and the pore shape.<BR>(2) The Young's modulus of the pulse electric current sintered body was dependent on the porosity, and independent on the carbon content, the particle size and the sintering condition. (3) The Young's modulus of the pulse electric current sintered body was smaller than that of the vacuum sintered body at same porosity.
