In order to deeply understand the high temperature deformation behaviors of Cu-0.23%Al2O3 (volume fraction) alloy, the changes of flow stress and microstructure for this alloy after deformation at high temperatures were investigated by using the Gleeble-15 ...
Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...
Geotechnical experimental observations of the influence of strain rate on the mechanical behaviour of soft soils express fundamental microscopic processes. The main macroscopical displays are creep, relaxation and strain-rate effect on strength. With these ...
During casting of aluminum alloys, the partially solidified material is submitted to thermally induced strains that can lead to severe casting defects, such as hot tearing. In this work, carried out in the frame of the European project VIR[CAST], the rheol ...
We investigate the fragmentation of an elastic visco-plastic ring in the one-dimensional framework. The governing equations include the effects of large deformation, geometric softening, hydrostatic pressure and material's viscoplasticity. Linear perturbat ...
In this paper, the behaviour of the tantalum subjected to a complex range of thermomechanical solicitations is studied and modelled. The objective of this work is the prediction of microstructure evolution of a tantalum part that is cold flow-formed, then ...
A comparison of experimental observations and computer simulations shows that trends in the occurrence and severity of center cracks in direct-chill (DC) cast ingots due to different initial casting speed histories may best be explained by the changes in v ...
The present thesis work provides new insight into the generation of allylmetal species and into their reactivity toward electrophiles. endo-Allylpotassiums are known to be more stable than their corresponding exo-isomers. The ring strain of methylenecycloa ...
Constant strain-rate and creep tests have been performed on poly-quasicrystalline specimens of the icosahedral Al-Cu-Fe system. Three temperatures (870, 960 and 1000 K) have been investigated by creep for samples predeformed at constant strain-rate before ...
This thesis deals with a laboratory study of heterogeneous reactions involving bromine and chlorine containing reservoir species on alkali salt substrates which are relevant to the marine boundary layer, and on ice substrates which are relevant to the lowe ...
