Abstract Establishing of wrought aluminum alloys casting to manufacture is now a global trend, for example due to lower production costs compare to forging or due to the ability to produce parts with thinner sections and more complex shapes. The aim of using these alloys in the foundry industry is in particular the creation of castings with higher mechanical properties than achieve castings made of standard casting aluminum alloys. Most often are cast wrought aluminum alloys of the 2xxx, 6xxx and 7xxx series. In the experiment, an alloy EN AW-2024 has been cast by modified technology of casting with crystallization under pressure. They were measured basic mechanical properties of the castings in the as-cast state and after heat treatment.

AbstractBy using the wrought aluminum alloys can be created castings with higher mechanical properties than the castings made of standard foundry aluminum alloys, but it is necessary to handle the process of making sound castings without any defects such as hot tears and shrinkage porosity. In experiments, we have been studied of wrought aluminum alloy EN AW-2024 which has been processed by the casting with crystallization under pressure with forced flow. Castings were heat treated by standard T6 heat treatment.

This article discusses the effects of various modifications on the properties of aluminum alloys for structural applications. The effect of reinforcing particles on the mechanical properties of wrought 6063 aluminum alloy arising from our previous works is extensively discussed to identify the most promising reinforcing particles. It also discusses the improvement in mechanical properties of 1200 aluminum alloy using silicon carbide particulates. The effect of micro-alloy additions on the mechanical properties is also outlined in this article based on the results from our previous experimental works. Effect of combining heat treatment and deformation on the mechanical properties of wrought aluminum alloys is also presented. Results presented show that particle reinforcement, deformation, and microelemental additions to aluminum alloy result in significant improvement in mechanical properties of the alloys considered. Addition of reinforcing particles of barite, silicon carbide, iron fillings, and electric arc furnace dust are found to impart improved tensile strength to aluminum alloy. The most outstanding finding is that synergy between particle addition, deformation, and heat treatment has a good prospect in the production of improved aluminum alloy materials for automotive applications.

Wrought aluminum alloys have wide variety applications in aerospace and automobile industries, due to their superior properties compared to casting aluminum alloys. Rheoforging is a modification of thixoforging, which starts directly from the liquid phase instead of reheating of a billet. In the present process, suitable semi-solid slurries of wrought aluminum alloys are prepared by the LSPSF (low superheat pouring with a shear field) rheocasting process within 25s. The effects of processing conditions on the degree of spherical grain refinement in 2024, 6082 and 7075 alloys are discussed. 2024 and 7075 alloys have been used in order to investigate rheoformability of high performance aluminum alloy. Experimental results show that rheoforging based on LSPSF process can produce relatively homogeneous microstructure throughout the cup-shaped component. However, high solid fraction of semi-solid slurry promotes metal flow and results in solid/liquid segregation. Subsequent optimized heat treatments raise significantly the mechanical properties. Future potentials and challenges to be solved are discussed.
