“…Pore removal makes the composite denser and gives it more room to resist tensile loads. Tensile strength is increased by strain fields created by deformation-induced dislocations [8]. The fact that grain development slows as the fraction of hybrid reinforcement particles increases aligns with the phenomena of increased mechanical strength with increasing reinforcement particle addition.…”

“…The microhardness and wear properties of wrought Al7075 alloy with SiC and Boron Nitride (BN) nanoparticles were investigated. The wear resistance increased by 61 percent, and microhardness increased by 45 percent in the manufactured composites [8]. Using mono and mixed additions of ceramic and metal particles as reinforcement, the corrosion and microstructural evolutions of surface composites were examined after the fabrication of surface composites by FSP.…”

“…The following method resulted in a significant reduction in grain size and the removal of casting faults, such as porosity [12]. Molybdenum as the metallic reinforcement and B 4 C as the ceramic reinforcement with Al1050 as the substrate was combined to fabricate metal matrix surface composites; the mono reinforcement showed a reduction in corrosion rate, whereas the combined reinforcement showed a galvanic effect [8].…”

Surface composites are viable choices for various applications in the aerospace and automotive industries. Friction Stir Processing (FSP) is a promising method for fabricating surface composites. Aluminum Hybrid Surface Composites (AHSC) are fabricated using the FSP to strengthen a hybrid mixture prepared with equal parts of Boron carbide (B4C), Silicon Carbide (SiC), and Calcium Carbonate (CaCO3) particles. Different hybrid reinforcement weight percentages (reinforcement content of 5% (T1), 10% (T2), and 15% (T3)) were used in fabricating AHSC samples. Furthermore, different mechanical tests were performed on hybrid surface composite samples with different weight percentages of the reinforcements. Dry sliding wear assessments were performed in standard pin-on-disc apparatus as per ASTM G99 guidelines to estimate wear rates. The presence of reinforcement contents and dislocation behavior was investigated using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) studies. The results indicated that the Ultimate Tensile Strength (UTS) of sample T3 exhibited 62.63% and 15.17% higher than that of samples T1 and T2, respectively, while the Elongation (%) of T3 exhibited 38.46% and 15.38% lower than that of samples T1 and T2, respectively. Moreover, it was found that the hardness of sample T3 increased in the stir zone compared to samples T1 and T2, owing to its higher brittle response. The higher brittle response of sample T3 compared to samples T1 and T2 was confirmed by the higher value of Young’s modulus and the lower value of Elongation (%).

“…As higher values of Jcorr represents the higher corrosion rate therefore, the base material shows the lower corrosion resistance compared to the NFP. 35 SZ of the NFP shows higher corrosion resistance because of the reinforcement elements and fine grain size. Table 6 shows the values of corrosion potential (Ecorr), corrosion current density (Jcorr), and corrosion rate (CR-mpy).…”

One of the major challenges encountered during friction stir processing (FSP) is the establishment of a process parameter window in order to achieve processed surfaces with an acceptable quality as it is an exhaustive task that involves enormous resources, time, and efforts. Sometimes this task is so difficult that the trial may run into futility. This work belongs to a theme of FSP that is not much reported in the literature. This is a maiden work to lay a roadmap for the FSP parameter range in a quick and effective manner. The present study results from first-hand experiments performed to produce surface composites on AA6063 alloy using a mixture of SiC + Fe + Mn + Sn as reinforcement in such a manner that a novice professional can pan out ways to identify and classify irregularities/defects, associate them with the causes and obtain feasible parameter window. In this work, a methodology for identification and selection of optimum tool speed (rpm), processing speed, and plunge depth has been demonstrated. The parameter window was established by analyzing main surface irregularities associated with the parameters and taking corrective modification to eventually arrive at the feasible range. The established range was validated through an experiment performed with the parameters lying within the established window. The validation was supported with microstructural characterization, micro-hardness measurement, thermal analysis, corrosion analysis, and the comprehensive analysis presented in this work has been done with the help of the image processing technique. Results show that grain refinement and homogeneous distribution of reinforcement present in the stir zone developed during FSP at the appropriate process parameters. Furthermore, grain refinement enhances the hardness by 28.29% and the corrosion resistance by 13.6%. The highest temperature that is, 423.25°C is achieved on the advancing side of the processed zone.

“…Therefore, structures that solidify quickly provide a better distribution of particles due to the smaller size of dendrites. On the other hand, once an alloy has a long solidification range and can form non-dendritic cells, advanced casting methods such as compo casting can be used [44][45][46].…”

This study investigates the effect of casting methods, content and size of reinforcing particles and heat treatment on the mechanical properties of A356-Al2O3 composite. First, composite samples were made by three methods: gravity sand casting, squeeze casting, and semi-solid compo casting, and then some of them were subjected to the T6 heat treatment. Test specimens were extracted from the samples, and their tensile and yield strength, elongation, and porosity were measured, analyzed, and compared. In addition, the microstructures of composites made by nano and micro scale reinforcing particles were studied and compared. It was concluded that the superior mechanical properties were obtained in samples made by semi-solid compo casting using nanoscale reinforcing secondary phase and subjected to the T6 heat treatment.
