“…It is well known that the uniform dispersion of reinforcement increase the dispersion strengthening, fine-grained alloy exhibits more resistance to deformation and substantial strengthening. 58 The difference in thermal expansion coefficient between reinforcement and matrix causes the additional dislocations and so the dislocation mobility is blocked by the reinforcements, which further increases the strength of composites. Generally, the phases act on the distortion fields of stress and strain alteration that brings about the mismatch between the Al alloy matrix and precipitations during the process.…”

In this research, the aluminum (Al2024) matrix composites are reinforced with nano magnesium oxide (MgO) and multi-walled carbon nanotubes (MWCNTs). The aim of Al2024 alloy reinforced with MgO and MWCNTs is to reveal the effects of the reinforcement particle ratio on the microstructure and mechanical properties of the hybrid composites, to find the optimum hybrid ratio, and to form a stronger hybrid composite. The composites with the different hybrid ratios are produced via stir casting method. The theoretical and measured densities and porosity content of the composites are studied. The microstructure and fracture surface of the composites are examined by optical microscopy, scanning electron microscopy (SEM), and electron dispersive spectrum (EDS). The hardness, compression, and tensile properties of the composites are studied in this work. Results indicated that the hardness of the aluminum (Al) matrix composites (AMCs) is significantly improved after the reinforcement with MgO and carbon nanotube (CNT), and also heat treatment of T6. The stress–strain curve of the composites is tested by a material testing machine. The maximum tensile and compression strengths are obtained at Al2024-0.2 wt.% (MgO 50% + CNT 50%) the composite as 226 MPa and 684 MPa, respectively .The hardness, compression, and tensile strengths of the hybrid composites are higher than 1.51, 1.39, and 1.31 than that of the base metal. After heat treatment of T6, the maximum harness, compression, and tensile strengths are obtained by 102 HB, 730 MPa, and 277 MPa, respectively, which are 1.82, 1.49, and 1.61 times higher hardness than that that of the base Al2024 alloy. The main strengthening mechanism of nano-MgO particles and MWCNTs-reinforced Al2024/MgO/CNTs composites is observed by the precipitation strengthening mechanism.

“…The oxide layer prevents direct contact between the test sample and the abrasive surface helps in reducing the wear rate. 28 The addition of TiB 2 reinforcement in the magnesium matrix enhances the resistance against deformation of the surface materials as the hardness of the materials increases. The wear resistance also increases due to an increase in temperature resistance properties by the addition of ceramic reinforcements.…”

“…The observations are in accordance with our previous experimental study, in which a suitable explanation for the abrasive wear behaviour of RZ5/TiB 2 composites at each parametric condition has been provided. 28 In the current research, the Taguchi method is adopted to analyze the effect and quality characteristics of control factors on the tribological behaviour of RZ5/ TiB 2 composites. In this study, the experimental results are transformed into signal-to-noise ratio (S/N ratio), and lower-the-better quality characteristics are utilized to analyze the effect of wear parameters on weight loss and coefficient of friction of RZ5/TiB 2 composites.…”

In the present study, the statistical analysis on tribological behavior of RZ5/TiB2 magnesium-based metal matrix composites is carried out using Taguchi design and analysis of variance (ANOVA) technique. Taguchi analysis using signal-to-noise ratio indicates that the sliding distance and wt.% TiB2 are the most significant factors in evaluating weight loss and coefficient of friction, respectively. The regression equation is formulated utilizing the ANOVA technique to study the output responses based on the input abrasive wear test experimental results. The regression equation is validated through a comprehensive study taking a series of abrasive wear tests and indicates the percentage deviation of regression modeling is in the range of ± 10%. The individual and combined effect of wear parameters on tribological behavior are investigated through the main effect plots and response surface plots. The micrograph of the worn surface of RZ5/TiB2 composites is studied using field emission scanning electron microscope (FESEM), indicating the formation of an oxide layer on the worn surface.

The present research deals with the modeling of wear performance of AA5052 metal matrix composites (MMCs) reinforced by in-situ formed TiC particles using two methods, namely statistical-based non-linear regression and fuzzy logic system. A pin-on-disc apparatus is employed to obtain the wear data of the composites. Three different process parameters, namely weight percentage of TiC, sliding distance, and applied load are considered as the input variables, and the volumetric wear loss and coefficient of friction are taken as output variables of the wear process. Regression models are formulated to study the output responses based on the wear results. To check the significance and contribution of the various control parameters, analysis of variance method was performed. Further, confirmatory tests were also conducted to validate both the models. It has been observed that the sliding distance and applied load have shown a substantial effect on the volumetric wear loss. It is also observed that the coefficient of friction is found to be increased with the rise in the sliding distance. The novelty of the work lies in using fuzzy logic to establish the wear model for aluminum 5052 MMC. A comparative study is performed to analyze the prediction accuracy of the models for the wear characteristics of the aluminum composites. Consequently, this wear modeling investigation will give a better understanding the effect of parameters and the responses influence of wear phenomena of Al 5052/TiC composites, which further will help in developing wear components for industrial applications.
