- Abstract
This research investigates the dual role of Aluminium powder in stabilizing and improving Aluminium foam production via the melt route. By mixing Aluminium powder with titanium hydride (TiH₂) before adding it to the melt, the powder acts as both a stabilizer and a dispersing agent for TiH₂, enhancing the foam’s structural integrity. The mixing process introduces oxides into the melt, further stabilizing the foam. This method results in a more uniform distribution of TiH₂, which is essential for creating consistent and stable foams. The addition of Aluminium powder not only improves foam stability but also reduces defects and promotes a uniform cell structure, thereby enhancing the foam’s mechanical properties. These findings suggest that Aluminium powder’s dual functionality in stabilizing and dispersing leads to higher-quality foams, potentially expanding their applications in lightweight structural components. This technique presents a promising approach for manufacturing superior Aluminium foams with improved stability and structural performance. This research explores the challenges in producing aluminium foams, focusing on improving their stability and uniformity. We investigate the dual role of aluminium powder in enhancing aluminium foam production through the melt route. By mixing aluminium powder with titanium hydride (TiH₂) before adding it to the melt, the powder serves as both a stabilizer and a dispersing agent for TiH₂. This approach helps achieve a more even distribution of TiH₂, which is crucial for creating stable foams. Additionally, the mixing process introduces oxides into the melt, which further improves foam stability. Our findings show that the addition of aluminium powder not only enhances foam stability but also reduces defects, resulting in a uniform cell structure and improved mechanical properties. Overall, this study highlights that the dual function of aluminium powder leads to higher-quality foams, offering the potential for broader applications in lightweight structural components. This technique offers a valuable method for producing superior aluminium foams with better stability and structural performance.
