Abstract Introduction: This study examines the microstructural and mechanical improvements in AA6061 hybrid composites reinforced with agricultural marine waste materials: plantain fibre ash (PFA), Eucalyptus Wood Ash (EWA), Periwinkle Shell Powder (PSP). The goal is to enhance properties while promoting sustainable manufacturing. Methods Hybrid were fabricated by varying PFA, EWA, PSP weight percentages. Microstructural analysis was conducted using Scanning Electron Microscopy (SEM) energy dispersive spectroscopy (EDS). Fourier Transform Infrared Spectroscopy (FTIR) used assess material integration, hardness tests performed evaluate improvements. Results SEM revealed uniform particle dispersion, EDS indicated compositional changes that contributed improved properties. composite 5% PSP, 3% 2.5% PFA exhibited a 224% increase compared base AA6061. FTIR confirmed successful integration of organic inorganic components, enhancing thermal stability corrosion resistance. Conclusion Reinforcing significantly its hardness, wear resistance, stability, demonstrating potential these eco-friendly for advanced engineering applications

Magnesium-based materials, which are known for their light weight and exceptional strength-to-weight ratio, hold immense promise in the biomedical, automotive, aerospace, military sectors. However, inherent limitations, including low wear resistance poor mechanical properties, have driven development of magnesium-based metal matrix composites (Mg-MMCs). The pivotal role powder metallurgy (PM) fabricating Mg-MMCs was explored, enhancing corrosion characteristics. characteristics depend upon fabrication methodology, composition, processing technique, reinforcement added to magnesium. PM is identified as most efficient due its ability produce near-net shape with high precision, cost-effectiveness, minimal waste. Furthermore, enables precise control over critical parameters, such compaction pressure, sintering temperature, particle size, directly influence composite's microstructure properties. This study highlights various reinforcements, mainly carbon nanotubes (CNTs), graphene nanoparticles (GNPs), silicon carbide (SiC), hydroxyapatite (HAp), effects on improving wear, resistance, strength. Among these, CNTs emerge a standout enhance multiple properties when used at optimal fractions. Further, this delves into interaction between types emphasizing importance uniform dispersion preventing porosity durability. Optimal conditions, pressure 450 MPa, temperatures 550 600 °C, times 2 h, recommended achieving superior performance. Emerging trends nanostructures bioactive particles, also discussed, underscoring potential widen application spectrum Mg-MMCs.

To provide insight into the interface structure in Ti particle-reinforced Mg matrix composites, this study investigates inherent Mg/Ti formed during solidification of supercooled melt on a (0001)Ti substrate using ab initio molecular dynamics (AIMD) simulations and density function theory (DFT) calculation. The resulting exhibits an orientation relationship 0001Mg//0001Ti with lattice mismatch approximately 8%. Detailed characterizations reveal occurrences 0001Mg plane rotation vacancy formation to overcome at while allowing atoms occupy energetically favorable hollow sites above atomic layer. diffusion behaviors rare-earth elements Gd Y was examined climbing image nudged elastic band (CI-NEB) method, demonstrating strong segregation tendency towards promoted by structure. Additionally, calculated Griffith work indicates enhanced interfacial adhesion due Y, which is beneficial for mechanical properties composite.

The study explores the impact of fly ash and nanoparticle reinforcements (TiO 2 , hBN, B 4 C) on magnesium alloy properties. Fly increases porosity reduces density. All reduce conductivity, C significantly decrease thermal expansion. This is attributed to particles' barrier effect, lower CTEs, ability promote uniform particle dispersion. distribution reinforcing particles varies, with hBN showing most even improve homogeneity, enhancing microhardness, exhibiting significant enhancement 72%. composite materials show increased compression strength, improvement over 50%. Mg hybrid composites display higher longitudinal shear velocities than pure Mg. shows substantial increase, a 30% rise in velocity 22% increase velocity. Moreover, all exhibit larger Young's moduli demonstrates notable enhancement, 50% modulus 45% modulus. These enhancements result from composites' heightened rigidity decreased mass caused by reinforcements, further amplified optimized spatial particles.
