Abstract
The ever-growing demands of modern mechanical applications necessitate the development of materials with superior mechanical properties. In this research, we delve into the creation and evaluation of Aluminum Metal Matrix Composites (Al MMCs) made via the powder metallurgy route, reinforced with both micro and Nano-scale particles. The key aim is to investigate the possible cooperative effects of this dual reinforcement approach on the mechanical behavior of the composite. Traditional aluminum MMCs, which are reinforced with either micro or Nano particles, have been well researched due to their unique benefits. Nevertheless, there is little information about how combining these levels of reinforcements would affect the resultant composite. In particular, it has been suggested that a combination of these two scales of reinforcement may introduce ductility-strength balance overcoming some drawbacks associated with only nano-reinforced systems in terms of reduced ductility In selecting micro and Nano particles proper care was taken so as to ensure uniform dispersion during blending powders together. Powder metallurgy was adopted for even distribution of reinforcements by optimizing compaction and sintering parameters. Elaborate mechanical tests such as tensile, compression and flexural tests were done and electron microscopy was used to analyze the microstructure. Additionally wear and fracture mechanics studies were carried out to determine suitability for high-performance applications. There have been encouraging initial results showing an increased trade-off in hardness versus toughness as seen in produced composites. Moreover, a noticeable improvement in wear resistance was observed, making it a viable contender for applications demanding prolonged durability. This research not only extends the knowledge frontier of Al MMCs but also paves the way for the practical implementation of such materials in industries seeking advanced material solutions.
