“…Composite reinforced with 3, 6, and 9 vol.% AlN has an average SDAS of 28 µm, 18 µm, and 10 µm respectively. It may be due to the uniform distribution of AlN particles by UCT and heterogeneous nucleation by AlN particles in the A356 matrix [5,7]. Fig.…”

“…Metal matrix composites (MMCs) are considered as a promising class of materials for engineering applications due to their unique combination of properties, resulted by the incorporation of reinforcement particles within the selected metallic matrix. Aluminum matrix composites, in particular, have attracted substantial interest owing to their outstanding mechanical properties, excellent thermal conductivity, and low density, which makes them suitable for a wide range of applications in aerospace, automotive, and electronic industries, among others [1][2][3][4][5][6][7][8][9]. One of the commonly used reinforcement particles in aluminum composites is aluminum nitride (AlN), which exhibits excellent thermal stability, high hardness, low density, good chemical and thermal stability.…”

Al-7Si-0.4Mg /AlN composites were successfully prepared by ultrasonic-assisted stir casting process. It was noticed that the ultrasonic treatment and incorporation of AlN particles were found to significantly improve the mechanical and wear properties of the matrix by grain refinement. The grain refinement and improved distribution of AlN particles in the Al-7Si-0.4Mg matrix aided in improving the tensile strength of the composites by about 32 % without appreciable decrease in ductility. Wear rate and friction coefficient was observed to decrease with increase in vol.% of AlN particles.

“…Hardness value tends to enhance from 70 BHN for A356 alloy to 94 BHN for 9 vol% zircon addition. This significant improvement in hardness can be credited to the uniform distribution of hard zircon particles in matrix metal and generation of dislocations at the matrix particle boundary for the period of the solidification owing to the coefficient of thermal expansion difference among Al matrix and Zircon Particles [50][51][52][53].…”

A356 Aluminium Alloy-Zircon composites were synthesized through the stir casting technique by introducing different volume fractions of zircon particles (3, 6, and 9 %). Stir casting process was carried out at the stirring speed of 600 rpm and stirring time of 10 minutes. The microstructure of the composites showed an even distribution of zircon particles. The composites' hardness improved with an increase in vol.% of zircon constituent part. Wear loss against different sliding distances and load was investigated through a Pinon-Disc wear testing apparatus with an L16 orthogonal array. Taguchi's parameter optimization demonstrated that material loss was influenced to a significant extent by adding Zircon. Wear resistance of the synthesized composite was investigated and verified using Analysis of Variance (ANOVA). Zircon content (39.33%) was found to be the most influencing factor on wear loss, followed by the applied load (36.80%) and sliding distance (21.54%). Zircon improves the properties of the composite through restricting the growth of dendritic arms in A356 alloy. In addition, reinforcement particles enhanced the strengthening of the composites through Orowan mechanism by inhibiting the movement of dislocations. ANOVA technique was successfully used to examine the effect of individual parameters on wear loss of A356 alloy-Zircon composites MMCs.

“…The ultimate tensile strength (UTS) and percentage elongation (EL) responses were analyzed and optimized by response surface methodology (RSM)-integrated grey relational analysis (GRA) analysis (Murugan and Ahmed, 2019). TOPSIS approach was used to optimize hardness and impact energy simultaneously (Suganeswaran et al , 2023). Uday et al used artificial neural network in conjugation with RSM for getting superlative output (Uday and Rajamurugan 2023a, 2023b).…”

Purpose This paper aims to determine the optimum parametric settings for yielding superior mechanical properties, namely, ultimate tensile strength (UTS), yield strength (YS) and percentage elongation (EL) of AZ91D/AgNPs/TiO2 hybrid composite fabricated by friction stir processing. Design/methodology/approach An empirical model has been developed to govern crucial influencing parameters, namely, rotation speed (RS), tool transverse speed (TS), number of passes (NPS) and reinforcement fraction (RF) or weight percentage. Box Behnken design (BBD) with four input parameters and three levels of each parameter was used to design the experimental work, and analysis of variance (ANOVA) was used to check the acceptability of the developed model. Desirability function analysis (DFA) for a multiresponse optimization approach is integrated with response surface methodology (RSM). The individual desirability index (IDI) was calculated for each response, and a composite desirability index (CDI) was obtained. The optimal parametric settings were determined based on maximum CDI values. A confirmation test is also performed to compare the actual and predicted values of responses. Findings The relationship between input parameters and output responses (UTS, YS, and EL) was investigated using the Box-Behnken design (BBD). Silver nanoparticles (AgNPs) and nano-sized titanium dioxide (TiO2) enhanced the ultimate tensile strength and yield strength. It was observed that the inclusion of AgNPs led to an increase in ductility, while the increase in the weight fraction of TiO2 resulted in a decrease in ductility. Practical implications AZ91D/AgNPs/TiO2 hybrid composite finds enormous applications in biomedical implants, aerospace, sports and aerospace industries, especially where lightweight materials with high strength are critical. Originality/value In terms of optimum value through desirability, the experimental trials yield the following results: maximum value of UTS (318.369 MPa), maximum value of YS (200.120 MPa) and EL (7.610) at 1,021 rpm of RS, 70 mm/min of TS, 4 NPS and level 3 of RF.
