| Abstract Scope |
Pure aluminum is virtually always alloyed with specific elements to improve its mechanical and physical properties. Alloying elements are also added to reduce the impact of the presence of impurities which will inevitably be exacerbated by recycling activities. The addition of alloying elements in liquid aluminum in the form of tablets, compacted powders, master alloys and scraps is a challenging task. These solid ingredients need to completely dissolve into the melt without oxidizing or volatilizing while limiting the undesirable transfer of inclusions and impurities. Sustainable alloying practices involve limiting the operating temperature of the melting furnace, decreasing the synthesis time, avoiding the use of excessively pure and energy-intensive ingredients as well as increasing the recycled content. This work reports new experimental data on the dissolution kinetics in liquid aluminum of a variety of alloying ingredients under static and dynamic conditions. Kinetic models to describe their dissolution rates are proposed. |
