Production of high porosity Zn foams by powder metallurgy method

摘要: Open-cell Zn foams with 74–92% porosity were fabricated by space holder technique, including compacting spherical carbamide granules coated powders followed leaching the and sintering. The role of compaction sintering parameters on pore structure, cell wall integrity compressive properties was investigated. results show that yield strength modulus elasticity decrease a good compatibility Gibson–Ashby model cellular solids is discovered. optimum structure mechanical are achieved at 300 MPa for 2 h 410°C.
