Fracture behavior of low-density replicated aluminum alloy foams (2008)
Amsterdam, E., Goodall, R., Mortensen, A., Onck, P. R.
Tensile tests have been performed on replicated aluminum alloy foams of relative density between 4.5% and 8%. During the test the electrical resistance was measured with a four-point set-up and the...
Microcellular aluminium? Child's play! (2007)
An innovation (patent pending) in the NaCl-based replication process for the manufacture of microcellular aluminium is presented that overcomes the limitations with the conventional method regarding...
Sintering of NaCl powder: Mechanisms and first stage kinetics (2006)
Goodall, R., Despois, J. F., Mortensen, A.
Isothermal NaCl sintering experiments are conducted between 500 and 790 degrees C on powders 75, 100, 150 and 400 mu m in average diameter. Along with literature data, the results are compared with...
The electrical conductivity of microcellular metals (2006)
Goodall, R., Weber, L., Mortensen, A.
The electrical conductivity of metallic foams varies strongly with porosity. Data are presented for replicated open-pore microcellular metal over a wide range of relative density. These data,...
Generalised Symmetries and the Ermakov-Lewis Invariant (2004)
Generalised symmetries and point symmetries coincide for systems of first-order ordinary differential equations and are infinite in number. Systems of linear first-order ordinary differential...
