Relationship between elongation and porosity for high porosity metal materials
（State Key Laboratoryfor Corrosion and Protection, Institute of Corrosion and Protection of Metals, The Chinese Academy of Sciences, Shenyang110015, P.R.China）
Abstract:A simplified model was proposed targeting at the isotropic high porosity metal materials with welldistributed structure. From the model the mathematical relationship between elongation and porosity was deduced for those materials, and the relationship formula was derived generally for actual high porosity metals at last, whose validity is supported by the representative experiment on a nickel foam prepared by electrodeposition.
Key words: high porosity metal material; elongation; porosity
