Creep of aluminium-magnesium open cell foam

Andreas Mortensen, Frédéric Diologent

Aluminium-5 wt.% magnesium open cell foam produced by replication and tested in tension at 300, 350 or 450 degrees C creeps at rates between 10(-3) and 10(-8) s(-1). The behaviour of the foam matches that of the alloy from which it is made: three-power law ...

Uniaxial deformation of microcellular metals: model systems and simplified analysis

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

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 ...

Microstructure, Strength and Creep of Aluminium-nickel Open Cell Foam

Andreas Mortensen, Frédéric Diologent, Yves Conde

Al-6.4 wt% Ni open-cell foams produced by replication are tested in compression and in tension at room temperature and creep tested in tension at 450C. The mechanical behaviour of this foam at room temperature is consistent with that observed for other ope ...

Fracture toughness of TiAl alloys: A comparison of two gamma-a2 structures

Andreas Mortensen, Frédéric Diologent, Nicolas Vincent Barbi

Toughness measurements of a Ti-45Al-2N4u-2Nb + 0.8%vol TiB2 alloy with a. near fully lamellar microstructure and a Ti-46Al-8Nb alloy with a convoluted microstructure are performed at 650 degrees C under vacuum according to ASTM Standard E1820. Respective v ...

Temperature dependence of lattice mismatch and gamma' volume fraction of a fourth-generation monocrystalline nickel-based superalloy

Frédéric Diologent

The strain distribution in a new generation nickel-based single crystal superalloy has been determined in the temperature range 293K–1598K. Measurements have been performed using diffraction of high energy synchrotron radiation (150keV, λ = 0.008 nm) to de ...
