Recrystallization behavior of multi-directionally forged over-aged and solution treated Al-Cu-Mg alloy during non-isothermal annealing

Roland Logé

The recrystallization behavior of an Al-Cu-Mg alloy is investigated in multi-directionally forged over-aged and solution treated alloys, during non-isothermal annealing. Deformation and non-isothermal annealing are performed with a Gleeble 3800 thermo-mech ...

Micromechanics of Amorphous Metal/Polymer Hybrid Structures with 3D Cellular Architectures: Size Effects, Buckling Behavior, and Energy Absorption Capability

Stefano Mischler, Johann Michler, Cédric Frantz

By designing advantageous cellular geometries and combining the material size effects at the nanometer scale, lightweight hybrid microarchitectured materials with tailored structural properties are achieved. Prior studies reported the mechanical properties ...

Microstructural stability of ODS steels in cyclic loading

Cécile Hébert

The remarkable microstructural stability of high chromium steels prepared by powder metallurgy and strengthened by dispersion of nanometric yttrium oxides in cyclic loading at high temperatures is reported. Contrary to the continuous cyclic softening and p ...

Thermal and damping behaviour of magnetic shape memory alloy composites

Véronique Michaud, Susanne Glock

Single crystals of ferromagnetic shape memory alloys (MSMA) exhibit magnetic field and stress induced strains via energy dissipating twinning. Embedding single crystalline MSMA particles into a polymer matrix could thus produce composites with enhanced ene ...

Fatigue design criteria for strengthening metallic beams with bonded CFRP plates

Alain Nussbaumer, Elyas Ghafoori, Masoud Motavalli, Mario Fontana

Different failure criteria used to prevent fatigue crack initiation in metallic members are described. A series of closed-form analytical solutions were developed to predict the fatigue resistance of metallic beams after strengthening with carbon fiber-rei ...

Designing laminated metal composites for tensile ductility

Andreas Mortensen, Amaël Maximilien Cohades, Arda Cetin

This contribution draws practical implications of a recently published estimation of the tensile ductility in laminated composites made of two ductile materials, typically metals or alloys, which harden as both the strain and the strain-rate increase. To t ...

Wetting of Ga on SiOx and Its Impact on GaAs Nanowire Growth

Gözde Tütüncüoglu, Heidi Andrea Potts, Federico Matteini, Fauzia Jabeen

Ga-assisted growth of GaAs nanowires on silicon provides a path for integrating high-purity III-Vs on silicon. The nature of the oxide on the silicon surface has been shown to impact the overall possibility of nanowire growth and their orientation with the ...
