摘要：
The influence of steam treatment on elastic properties of sintered iron parts was investigated. After steam oxidation, the mechanical properties results varied; there is a great increase in hardness, a porosity reduction, and an improvement of tensile strength in any direction. As literature reports a lot of papers about the relationship between ultrasound propagation velocity and mechanical properties of porous metal, in this paper this method is extended to sintered steam oxidised parts; in particular, the relationship between ultrasound propagation velocity and Young's modulus after treatment.
