Purpose Engineers and scientists are searching for novel materials with high performance on all aspect points of view for the applications including marine, aero and automobile fields. AA8090 aluminum alloy is one of the materials used in aero industries for aircraft construction because of its weight reduction ability. However, the AA8090 alloy has a drawback such as low wear resistance that affects the life time of material; hence, it should be addressed. The purpose of this investigation is to improve the wear resistance of AA8090 alloy. Design/methodology/approach In this investigation, AA8090 aluminum alloy metal matrix composite was fabricated using different types of carbide nanoparticles such as vanadium carbide (VC), Cr3C2 and Mo2C by stir casting method and tribological and mechanical behaviors were studied. Findings Mechanical studies showed that the S1 sample displayed the maximum hardness of 142 HV and maximum tensile strength of 857 MPa because of the inclusion of hard VC particles. Tribological studies revealed that S1 sample showed high performance. A least wear rate of 0.003915 × 10–3 mm3/m was noted for S1 sample, which is 71% lower than the wear rate of S0 sample. Further, a least mass loss and lower coefficient of friction of 0.00152 g and 0.2, respectively, were observed for S1 sample because of its high hardness and high wear resistance because of the stuffing of high-hardness VC particles. Hence, it is concluded from this study that S1 sample, i.e. AA8090/VC, could be a better candidate for aerospace applications as it showed good tribological and mechanical properties. Originality/value To the best of the authors’ knowledge, this work is original and novel in the field of metal matrix composite which deals with the effect of hybridization on the wear performance of the aluminum alloy composites.

“…Friction stir processing (FSP) is another promising solid-state method that is able to produce MMCs. However, this method is primarily used to produce surface composites [5,6] and requires extensive process optimization and simulation to understand the effects of those parameters on the homogeneity of the composite [7] . Liquid-state methods usually involve different ways of introducing the reinforcement particles into the liquid melt [8] .…”

Nowadays, additive manufacturing (AM) technologies have been widely used in construction, medical, military, aerospace, fashion, etc. The advantages of AM (e.g., more design freedom, no restriction on the complexity of parts, and rapid prototyping) have attracted a growing number of researchers. Increasing number of papers are published each year. Until now, thousands of review papers have already been published in the field of AM. It is, therefore, perhaps timely to perform a survey on AM review papers so as to provide an overview and guidance for readers to choose their interested reviews on some specific topics. This survey gives detailed analysis on these reviews, divides these reviews into different groups based on the AM techniques and materials used, highlights some important reviews in this area, and provides some discussions and insights.

Friction stir processing (FSP) is a modern manufacturing strategy for improving the surface characteristics of materials by modifying their surface via localized plastic deformation. This research focuses on optimization process parameters for tungsten carbide-reinforced 6061 aluminum alloy surface composite using FSP. The effect of the process parameters including tool rotational speed, transverse feed, number of passes, and tungsten carbide particles volume fractions, on ultimate tensile strength (UTS) and grain size of fabricated AA6061/WC surface nanocomposites are investigated. For four factors and three levels, the L27 Taguchi technique is used to formulate the experimental design. The analysis of variance (ANOVA) is used to determine the significance and the percentage contribution of each parameter. The desirability approach is used to optimize the process parameters in terms of tensile strength and average grain size. The results indicate that the proper selection of FSP parameters results in a homogeneous distribution of the WC particles throughout the matrix thereby producing a defect-free AA6061/WC nanocomposite without voids. Also, the severe plastic deformation and heat generation during FSP causes the breaking of coarse particles, WC particles, elimination of porous holes and creates an ultrafine grain-sized structure via dynamic recrystallization. Furthermore, it was concluded that the transverse feed is the most significant factor for ultimate tensile strength with 40.1% contribution whereas the number of passes is the most significant factor for grain size with a 34.7% contribution. The optimum combination of the current process parameters is found to be 1800 rpm rotation speed, 120 mm/min transverse feed, 4.3636% volume fraction, and 3- pass for optimum values of UTS and grain size. The surface composite developed in this work is considered appropriate material for applications requiring lightweight and improved surface properties, such as aerospace, automotive, marine, defense and transportation industries.
