“…2 Furthermore, the fabrication of HMMCs has been done through several routes such as powder metallurgy, infiltration, microwave sintering, compocasting, and stir casting. 13–15 Stir casting has been one of the most suitable processes for producing MMCs because of its simplicity, proven process, lower cost of production, and mass production capability. 1 Moreover, stir casting incorporated with significant process parameters (i.e.…”

This paper investigated Al-based hybrid metal matrix composites (HMMCs) comprised of Al7075-(T6) base metal matrix doped with SiC+MoS2 reinforced particles for high-strength, lightweight, and wear-resistant applications. Taguchi’s design of L9 orthogonal array (OA) with three process variables having different levels (such as SiC particle (2.5, 3.5, and 4.5 wt.%), MoS2 particle (1.5, 2.5, and 3.5 wt.%), and stirring speed (580, 600, and 620 rpm)) has been selected for fabrication of Al-based HMMCs via an advanced vacuum-assisted stir casting route. The controlled porosity level and dry sliding wear behavior (i.e. wear loss) of fabricated hybrid composites at an ambient temperature of 35°C have been conducted. Besides, metallographic evaluation was inspected through optical microscopy, high-resolution FESEM, and SEM-EDS techniques. Furthermore, experimental outcomes obtained from Taguchi’s design of experimentation were optimized by analysis of variance (ANOVA); and also validated through an artificial neural network (ANN) modeling with a network topology of 3-10-2. The results concluded that a homogeneous dispersion of reinforced particles over the base metal matrix (with controlled both abrasive and adhesive wear mechanisms of worn surfaces). Moreover, a significant reduction in porosity level (up to 29.41%) and wear loss (up to 4.94%) of the proposed hybrid specimen (S4) as compared with an unreinforced specimen (S0). In addition, the predicted values obtained from the ANN model were confirmed in close proximity to Taguchi’s experimental outcomes (with less percentage error), which in turn certified the authentication of the constructed ANN model for the Al-based HMMCs.

This research aims to investigate the microstructural properties, tensile fractography, and wear characteristics of scrap aluminum engine head (SAEH) composites reinforced with fresh alumina catalysts (FAC) and spent alumina catalysts (SAC) derived from petrochemical industries. Utilizing the stir casting method, four composite variants were fabricated: SAEH + SAC, SAEH + FAC, LM25 + SAC, and LM25 + FAC. The materials were characterized through scanning electron microscopic (SEM) analysis, and the composition of FAC and SAC was detailed. The investigation delves into the wear properties through pin-on-disk tests conducted at different conditions. Tensile strength results revealed distinctive performance: SAEH + FAC = 208 MPa, SAEH + SAC = 217 MPa, LM25 + FAC = 92 MPa, and LM25 + SAC = 184 MPa. Fractography analysis provided insights into the fracture behavior, showcasing the influence of agglomerates, non-coherent interfaces, lack of wetting, grain refinement, and the presence of oxides. The wear behavior, evaluated under varying operating conditions, demonstrated that wear rates increased with escalating conditions and were generally higher for LM25-based composites than for SAEH-based composites. This study introduces the innovative use of SAC in composites, offers a comparative analysis between different materials, and provides a comprehensive understanding of wear behavior under diverse conditions, contributing to the advancement of metal matrix composites.
