摘要: Abstract The microstructure of aluminium foam produced by decomposing TiH2 in the stabilized melt can be modified heat treatment to improve mechanical properties cell wall. Different microstructures were developed through solutionizing and quenching followed thermal ageing treatment. Uniaxial compression tests performed on specimens understand as how wall influences energy absorption capability foam. It is found that solutionized sample has best (29.3 MPa) when compared as-foamed (13.2 MPa) aged samples (15.9 MPa). crack progression studies carried interrupted confirm detrimental influence cast dendritic structure lamellar Al2Cu precipitate formed during aging. results suggest extent aging depends precipitation behaviour matrix.
