| Abstract Scope |
Conventional manufacturing processes for aluminum matrix composites (AMCs) involve complex procedures that require unique equipment and skills at each stage, increasing the process costs. This study outlines an innovative, straightforward approach for fabricating AMCs that circumvents the complexities and high costs associated with traditional manufacturing techniques. This novel method involves heating a blend of aluminum powder and ceramic reinforcement under a nitrogen atmosphere, which triggers surface modification through nitridation. This process leads to the formation of nitrides on the aluminum powder's surface, facilitating a rapid local temperature increase and partial melting of the aluminum. The molten aluminum then fills the spaces between the powder and reinforcement, consolidating the mixture without the need for external pressure. This technique allows for the creation of AMCs with diverse reinforcements, potentially lowering manufacturing temperatures due to the exothermic nature of nitridation and avoiding unwanted reactions.
