Fatigue and cyclic creep of replicated microcellular aluminium

Andreas Mortensen, Frédéric Diologent, Sébastien Philippe Soubielle

The cyclic behaviour of 400 mu m pore size replicated aluminium foam is assessed in tension-tension fatigue with a stress ratio equal to 0.1, keeping the load amplitude constant, for relative density values comprised between 0.175 and 0.220. The number of ...

Creep of replicated microcellular aluminium

Andreas Mortensen, Frédéric Diologent, Sébastien Philippe Soubielle

Open-pore replicated microcellular 99.99% pure aluminium is tested in tensile creep, varying the temperature from 150 to 450 degrees C, the applied stress from 0.15 to 0.5 MPa, and the relative density from 0.14 to 0.28. Tensile creep curves are of classic ...

On measured activation volumes as relevant to ratcheting or cyclic creep

Andreas Mortensen, Sébastien Philippe Soubielle

We consider a material having a constant true activation volume and estimate the apparent activation volume that it displays in cyclic creep or ratcheting. We show that cyclic stresses have an effect on the measured value, and that this can be accounted fo ...

Uniaxial deformation of microcellular metals: model systems and simplified analysis

Jean-François Despois, Randoald Müller, Andreas Mortensen, Yves Conde, Etienne Combaz, Frédéric Diologent, Sébastien Philippe Soubielle

Microcellular aluminium can be produced by a process known as replication; this involves the infiltration of a packed bed of NaCl particles which are subsequently leached after metal solidification. The resulting material features a uniform distribution of ...
