“…The observed value of mechanical properties of GNP/Al MMC was 256.8 and 210.6 MPa for tensile and yield strength respectively. 41 Many studies have been reported on hexagonal boron nitride (hBN) particle reinforcement in AA7150 Al MMC. The results have shown that the increase in the loading content of hBN up to 1.5 wt% has improved the ultimate tensile and wear properties of MMC but a higher reinforcement ratio led to a decrease in the MMC performance due to bigger agglomerations around the grain boundaries.…”

Conventional manufacturing processes such as casting, forming, welding, machining, etc., have been optimized using different improvement techniques in the last few decades. The alterations in these processes have led to more efficient and productive manufacturing practices for the industry. One of these modification techniques is the deployment of ultrasonic vibrations in conventional manufacturing processes. In the last few decades, ultrasonic vibration assistance to manufacturing processes has seen an uprise and was the point of attraction for different research groups. Several improvements by utilizing ultrasonic vibration in manufacturing practices have been reported by the authors in the past. In this article, an attempt has been made to review all the reported techniques for different conventional processes viz. casting, forming, machining, and welding. The article outlines different research findings from the extensive work on ultrasonic vibration assistance showcasing the improved mechanical and morphological properties. The improvisation in the performance parameters viz. friction reduction, stress reduction, tool wear, surface finish, and grain structure has been witnessed by ultrasonic assistance in contrast to simple manufacturing processes. The outcomes have been summarized along with the optimized set of parameters from various studies.

“…This sole employment of h‐BN and GNPs during ultrasonic casting of 2D platelet reinforced metal matrix composites renders an additional limitation. The densities of h‐BN, 2.1 gcm −3 , [ 6 ] and GNP, 2.2 gcm −3 , [ 13,14 ] are comparable to that of aluminum (Al), 2.7 g cm −3 , and thus intermix easily with the molten metal. On the other hand, the intermixing behavior of 2D layered reinforcements heavier than Al is entirely unexplored.…”

Role of Ultrasonic Treatment on Microstructure, Multiscale Mechanical, and Tribological Behavior of 2D Tungsten Disulfide Reinforced Aluminum Composites

et al. 2022

This article is the first report on the role of ultrasonic treatment (UST) on microstructural evolution, multiscale mechanical behavior, and tribological response in 2D tungsten disulfide (WS2) reinforced aluminum (Al6061) matrix composites. Delaunay triangulation calculations show that UST for 45 s enables a fourfold enhancement in the dispersion parameter of WS2 reinforcements in the Al6061 matrix from 0.08 to 0.32. Improved WS2 dispersion contributes to higher nucleation density with 52.7% grain refinement efficiency, achieving a fine‐grained Al6061–WS2 composite. The role of UST‐induced 2D reinforcement dispersion on the elastic deformation is established at progressively increasing length scales from individual grains to the bulk composite. It is accomplished by integrating the nanodynamic modulus mapping technique with a finite element modeling framework built on experimentally acquired microstructures and localized elastic moduli. It delineates a directly proportional relationship between UST‐induced dispersion and elastic modulus enhancement at all length scales from 10 to 700 μm. Excellent dispersion of the 2D layered WS2 homogenizes the tribological response of the composite material with a tenfold reduction in the volume of material lost during wear.

“…Janudom et al [ 21 ] investigated the feasibility study of die-casting of ADC12 aluminium alloy in a semi-solid state. The effect of reinforcement with graphene nanoplates (GNPs) and ultrasonication on microstructure and mechanical properties of ADC12 composites were examined by Xiong et al [ 22 ]. The optimal value of GNPs reinforcement was found to be 0.9 wt.%, and optimal ultrasonic time 12 min.…”

In this work, aluminium alloy ADC12 reinforced with various amounts of ZrB2 (0 wt.%, 3 wt.%, 6 wt.%, 9 wt.%) were synthesized by an in-situ reaction of molten aluminium with inorganic salts K2ZrF6 & KBF4. XRD, EDAX, and SEM techniques are used for the characterization of the fabricated composite. XRD analysis revealed the successful in situ formation of ZrB2 in the composite. From the SEM images, it was concluded that the distribution of reinforcement was homogeneous in the composites. A study of mechanical and tribological properties under the dry sliding condition of ZrB2-reinforced ADC12 alloy has also been carried out. It is seen that there is an increase in tensile strength by 18.8%, hardness by 64.2%, and an increase in wear resistance of the material after reinforcement. The ductility of the material decreased considerably with an increase in the amount of reinforcement. The composite’s impact strength decreased by 27.7% because of the addition of hard ZrB2 particulates.
