STRUCTURE AND COMPRESSIVE PROPERTIES OF IRON AND IRON-PHOSPHORUS PM FOAMS

摘要

Prospective materials for synthetic bone graft substitutes - iron and iron-phosphorus open cell foams - were prepared by impregnating an open-cell polyurethane sponge with suitable metal powder slurry, subsequent thermal removing the organic template, and final sintering the residual powder skeleton. The structure and compressive properties of resultant metallic foams were investigated. The results show that the samples behave as if they were solids made up of an interconnected network of ductile struts.
