Outline of Final Research Achievements |
Porous Zn-22Al superplastic alloy having cell microstructure of porous metals and fine crystal grain of superplastic metals has been manufactured. The samples fabricated through casting process with a foaming agent has the porosity of 80% and average pore size of 2.9 mm. Fine crystal grains with 2.2 micrometer size has been fabricated through solution heat treatment followed by artificial aging. Quasi-static and dynamic compression tests revealed that the porous Zn-22Al superplastic alloy has high strain rate sensitivity. Newly developed porous metal has a potential of energy absorbing material.
