    Journal of Materials Engineering and Performance, 2025
    The fabrication of aluminum metal matrix composites (AMMCs) plays a pivotal role in determining their suitability for marine applications, where materials are subjected to harsh environments, including saltwater exposure, high humidity, and fluctuating mechanical loads. Poor particle dispersion, agglomeration, and inadequate bonding between the matrix and reinforcements often result in localized corrosion, reduced wear resistance, and structural degradation, making conventional AMMCs less reliable in marine settings. The presence of defects such as porosity and uneven reinforcement distribution further compromises their mechanical integrity and long-term durability under corrosive marine conditions. To overcome these challenges, this study employed an innovative stir-ultrasonication-squeeze (SUS) casting technique to enhance the microstructural and corrosion properties of AA2014-nAl2O3 nanocomposites. Critical process parameters, including ultrasonic power (2250 W), ultrasonication time (16 minutes), pouring temperature (700 °C), squeeze pressure (150 MPa), and reinforcement content (2 wt.%), were systematically optimized to achieve uniform particle dispersion, grain refinement, and enhanced corrosion resistance. Advanced characterization using high-resolution scanning electron microscopy (HR-SEM) and optical microscopy (OM) revealed the mitigation of particle clustering and a refined grain structure with a minimum size of 43 µm under optimized conditions. Taguchi grey relational analysis (TGRSA) identified the influence of process parameters on corrosion performance, with ANOVA showing ultrasonication time as the most significant factor (11.5% contribution). Confirmation tests demonstrated optimal process conditions—2.248 kW ultrasonic power, 15.89 minutes ultrasonication time, 700.1 °C pouring temperature, 143 MPa squeeze pressure, and 1.95 wt.% reinforcement—leading to significant improvements in corrosion resistance, including a 14% reduction in salt spray corrosion rate and a 37% increase in grey relational grade (GRG). These findings underscore the potential of the SUS casting technique to address the traditional limitations of AMMCs, providing a pathway for developing corrosion-resistant materials tailored for marine and other extreme environmental applications.

  • TRIBOLOGICAL ENHANCEMENT OF AZ91D MAGNESIUM COMPOSITES USING ZRB2 CONCENTRATION AND AGEING TEMPERATURE FOR HIGH-PERFORMANCE LIGHTWEIGHT MATERIALS
    A. Gnanavelbabu, Prahadeeswaran M., Vinothkumar E.
    ASME International Mechanical Engineering Congress and Exposition Proceedings Imece, 2025
    Modern automobile engines require lightweight, wear-resistant materials for efficiency and durability. AZ91D Magnesium (Mg) alloy, known for its high strength-to-weight ratio and damping capacity, is a promising candidate for automotive applications. However, its poor wear resistance can lead to increased friction and accelerated component degradation. To address this, researchers have enhanced AZ91D with ZrB2 reinforcement (5, 10, and 15 wt.%) and ageing treatments to improve its tribological properties. The materials were fabricated using a Stir-assisted ultrasonication and squeeze casting process and subjected to a T6 heat treatment process at 170 °C-260 °C. The microstructural analysis confirmed a uniform ZrB2 distribution, while XRD validated the presence of intermetallic phases. Hardness testing showed improvements of 2.98%, 13%, and 11.56% for composites with 5, 10, and 15 wt.% ZrB2 at 230 °C, attributed to grain strengthening and β-phase refinement. Linear reciprocating wear tests under varying loads revealed significantly enhanced wear resistance, with the AZ91D + 10 wt.% ZrB2 (A2) composite showing an 89.90% improvement at 230 °C. SEM analysis of worn surfaces identified abrasion, oxidation, and delamination as primary wear mechanisms, with A2 exhibiting minimal wear damage due to refined grains, increased hardness, and a protective β-Mg17Al12 phase.

  • INTEGRATED IMPACT OF ZRB2/HBN CONTENT AND AGING TEMPERATURE ON SALT SPRAY CORROSION RESISTANCE OF AZ91D MAGNESIUM COMPOSITES FOR MARINE APPLICATIONS
    Gnanavelbabu A., Prahadeeswaran M., Vinothkumar E.
    ASME International Mechanical Engineering Congress and Exposition Proceedings Imece, 2025
    Magnesium (Mg) alloys are promising lightweight materials for marine applications due to their high strength-to-weight ratio and damping capacity, yet their practical use is limited by poor corrosion resistance. This study evaluates the corrosion performance of AZ91D-based hybrid composites reinforced with Zirconium diboride (ZrB2) and hexagonal Boron Nitride (hBN) particles, fabricated via an ultrasonication-assisted stir-squeeze casting method, followed by T6 ageing at 170, 200, 230, and 260 °C. Microstructural analysis using SEM and XRD confirmed uniform dispersion of thermally stable reinforcements and absence of intermetallic phases. The addition of ZrB2 and hBN increased the composites’ density and porosity while significantly enhancing hardness, with AZZH (AZ91D + 10% ZrB2 + 5% hBN) exhibiting the highest improvement at 230 °C. Salt spray corrosion testing in 3.5% NaCl over 24, 48, and 72 hours revealed AZZH as the most corrosion-resistant composite, showing up to 42.82% better resistance than the unreinforced alloy. The optimal ageing temperature was identified as 230 °C, offering up to 35.7% improvement over other conditions. Corroded surface SEM images indicated that ZrB2 provides superior corrosion protection over hBN by reducing pit and crack formation. These results show that reinforcement and heat treatment together improve the corrosion resistance of Mg composites for marine use.
  • ANTI-WEAR BEHAVIOR OF AZ91D MAGNESIUM COMPOSITES REINFORCED WITH ALLOYING ELEMENTS FOR AEROSPACE APPLICATIONS

    ASME International Mechanical Engineering Congress and Exposition Proceedings Imece, 2025
    The demand for lightweight aerospace materials is increasing to achieve better fuel efficiency, higher payload capacity, and improved performance. Magnesium (Mg) alloys, particularly AZ91D, offer high specific strength and excellent damping capacity, making them ideal for weight-sensitive components. However, their limited wear resistance hinders wider application. This drawback can be overcome by adding suitable alloying elements to refine the microstructure and enhance surface stability. In this study, Bi, Sb, and Sr were incorporated into AZ91D using ultrasonic-assisted stir squeeze casting followed by T6 heat treatment, and their properties were thoroughly evaluated. Results showed that Sr addition produced the finest grains (∼55 μm) through Al4Sr formation, as confirmed by SEM and optical microscopy, leading to improved reinforcement dispersion and dislocation resistance. XRD identified Mg3Bi2, Mg3Sb2, and Al4Sr phases with reduced β-Mg17Al12, indicating enhanced phase stability. ASr achieved the highest density (1.818 g/cm3), lowest porosity (0.33%), maximum hardness (70.3 VHN), and highest UTS (210.12 MPa) due to grain refinement and strong intermetallic bonding. Wear rate increased by 33.33% in AZD but only 18.18% in ASr, while COF decreased by 13.51% and 15.15% at 0.5 and 1.5 m/s. Worn surfaces of ASr showed smooth, shallow grooves, confirming superior tribological performance.
  • Investigating the wear performance of AZ91D magnesium composites with ZnO, MnO, and TiO2 nanoparticles

    International Journal of Advanced Manufacturing Technology, 2023
    In recent decades, there has been a notable advancement in the field of bioactive, biodegradable, and biocompatible metallic materials, particularly for applications in general surgery. Among these materials, magnesium alloy-based composites have gained popularity due to their excellent biological properties and adequate strength. However, their resistance to wear is still an area that requires further investigation. Therefore, this study examines the wear properties of stir-ultrasonic-squeeze-casted magnesium (AZ91D) composites, incorporating distinct nanoparticles such as ZnO, MnO, and TiO2. The Evaluation-based Distance from Average Solution (EDAS) approach is used to determine the optimal parameters. Additionally, an Analysis of Variance (ANOVA) is conducted to identify the crucial factors influencing the responses. The effect of process factors on the wear rate and Coefficient of Friction (COF) is then investigated using response surface plots. The confirmation assessments reveal that the optimal parameter conditions for the tribo process comprise a 50.0018 N applied load, a 1.4998 m/s sliding velocity, and the AZ91D + 1% TiO2 (ATO) composite utilization. The ANOVA findings demonstrate that the applied load significantly contributes to 67.3% of the wear performance. Subsequently, after determining the optimal condition, it is observed that the ATO composite, when exposed to temperatures above 150 °C, exhibits an abrupt increase in wear rate and COF due to the degradation of grain strength and the dissolution of the β-phase within the composite.
