| Abstract | Zinc-aluminium alloy bars and wires were successfully extruded in the liquid-solid state with a liquid fraction higher than 15%. Fully dense materials were obtained in this way with pressure lower than 100 MPa. The relationship between flow stress and solid fraction was obtained and the role of the liquid component in the deformation behaviour was clarified. Mechanical properties of the extruded material are presented and discussed with regard to the initial microstructure of the metals before deformation, i.e. the conventional dendritic structure and non-dendritic structure composed of solid spheroids dispersed in the remaining liquid obtained by stir-casting techniques. The microstructure of the extruded products was generally fine and a fibrous structure was easily observed particularly for the stir-cast material where primary solid spheroids were highly deformed. Optimization of these parameters leads to a desirable high-strength material. |
