Two-phase modelling of hot tearing in aluminium alloys using a semi-coupled method

Vincent Mathier

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 ...

Influence of the mould thermal expansion on composite stress build-up during curing

Jan-Anders Edvin Maansson, Véronique Michaud, Sébastien Lavanchy

The influence of the mould material on the build-up of internal stresses during autoclave cure of a unidirectional carbon fibre composite material was investigated using embedded optical fibre Bragg gratings. Four flat moulds (i.e. aluminium, steel, carbon ...

Replicated aluminium foam : processing and properties

Jean-François Despois

This thesis explores the processing and properties of microcellular aluminium-based materials produced by replication. It includes the development of a pressure infiltration process for net-shape component production, structural characterization of the foa ...
