The hot tearing of aluminium-copper alloys is a serious defect for the foundrymen. The grain refinement of these alloys allows to decrease their hot tearing susceptibility. The aim of this work is to better understand the hot tearing mechanism and th

The present work describes the microstructural evolution of an Al–4Cu alloy and its deformation response, as measured by the parallel plates technique. Specimens were heat treated to obtain a variety of Al2Cu dispersions, and deformed by extrusion

The results of an experimental investigation carried out with grain-refined AZ91 magnesium–aluminium alloys are presented. The microstructure of the material during partial remelting and holding in the semi-solid state was thus characterised togeth

Close to their melting point, metallic alloys containing a liquid phase can be described, in the high solid fraction range, as viscoplastic porous media saturated with liquid. In this article, a model is proposed in the general framework of the mixtu
