Abstract
Homogenization conditions of the AlCuMg alloys strongly influence the microstructure of ingots for extrusion process. In this work, the homogenization of 2014 and 2024 alloys intended for extrusion with a solution heat treatment on the press (T5 temper) was analyzed. The study describes the dependence of the material microstructure on the alloy chemical composition and the mode of homogenization treatment. The alloys with extreme content of the main additions were taken into consideration and the high-temperature homogenization procedure was proposed. Optical microscopy and SEM/EDS characterisation of the as-cast and as-homogenised samples was applied to reveal the most important microstructural features of the alloys and changes caused by the different heat treatments. Differential Scanning Calorimetry (DSC) analysis was also done to support metallographic observations. The homogenization of AlCuMg alloys at temperatures close to the solidus temperature allows us to obtain the structure without over-melting that could unfavourably affect the extrusions quality. Such homogenization enabled achieving the good uniform microstructure of the alloys with fine particles of intermetallic phases, what can facilitate their dissolution within deformation zone during extrusion process. The improved heat treatment of 2014 and 2024 ingots should make solution heat treatment on the press more effective and thus lead to increased strength properties of extrusions in T5 temper.
