“…Kuz'min et al [12] produced an Al-metal matrix composite with nano carbon (CNT) (in the range of 0.01 to 1.00 wt%) by powder metallurgy method, and they stated that the tensile test results were improved up to the addition of 0.1 wt.% CNT, then the CNT powders were agglomerated. In another study, Kuz'min et al [13] found Al 4 C 3 intermetallic in the microstructure investigations of nano carbon reinforced Al-metal matrix composites. They also emphasized that the electrical conductivity of the produced Al-CNT composite materials was very close to the cast material.…”

This paper investigated the wear performances of Y2O3 doped MA6000 (Ni-Cr-Al) alloy produced by mechanical alloying (MA). Produced, all powders were pre-formed by cold pressing and sintered in a vacuum environment. Sintered MA6000-X% Y2O3 superalloys were characterized by scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD) analysis, density, and hardness measurements. Wear tests of Y2O3 added MA6000 alloys were carried out in a block-on-ring type wear device. In the wear tests, the sliding speed of 1 ms-1 at room temperature (RT) was performed under five different sliding distances (200-1000m) and three different loads (5 N, 10 N, and 15 N). As a result of the studies, it was determined that the MA?ed MA6000 superalloy powders were homogeneous and flake shape. With the increase amount of Y2O3, hardness of these superalloys increased from 267 to 431 Hv, but the density slightly decreased. Different intermetallic/carbur phases such as Ni3Al, MoC are observed in all compositions. Wear tests show that weight loss and wear rate decreased, and friction coefficient (?) increased with the increasing amount of Y2O3 additive. Besides, it was determined that as the applied load increased in the wear test, the weight loss increased, but the wear rate and friction coefficient (?) decreased.

“…In contrast, an SAED pattern obtained at the interface revealed a ring pattern indicating the amorphous formation or a very fine nano-grain structure. The SAED ring pattern was well indexed to the AlFe 3 with a space group of Fm3m, which is thermodynamically stable [34,35]. Liu et al [22,27] also observed complex intermetallic AlFe phases at the interface zone such as AlFe, AlFe 3 , Al 5 Fe 2 , and Al 3 Fe.…”

Dissimilar Materials Welding with a Standoff-Free Vaporizing Foil Actuator between TRIP 1180 Steel Sheets and AA5052 Alloy

This paper mainly demonstrates an advanced type of the vaporizing foil actuator welding (VFAW) process between GPa-grade steel (TRIP1180) and aluminum alloy (AA5052-H32) without applying standoff. To secure a flying distance during the VFAW process, the preformed target sheet shaped like a circular indentation has been utilized. It is necessary to optimize process parameters integrated with geometrical design of the preform since the welding strength can be decreased beyond the optimum input energy in the standoff-free VFAW process. The welded surface was evaluated by SEM-EDS, XRD, EBDS, and TEM to analyze the welding mechanism and composition at the welding interface. The diffusion zone including the AlFe3 phase was observed at the welded interface which has high grain density due to the high-speed impact by increasing the welding strength, which leads to the perfect welding between the dissimilar materials.

“…Zirconium diboride is a high-quality ultra-high-temperature ceramic material that has outstanding physical, structural, transport, and thermodynamic properties. As a result, it can be used in a variety of applications, including refractory linings [25,26], electrodes [27], microelectronics [28], and cutting tools [29]. ZrB 2 is an excellent material for thermal protection systems due to its high melting temperature, chemical stability, and resistance to erosion/corrosion, as well as its exceptional electrical and thermal conductivity.…”

The process of Thermal spray is effective for creating a metal matrix composite (MMC) by embedding zirconium diboride reinforcement into a molybdenum matrix. Both materials Mo and ZrB2 have different characteristics, but they have good thermal shock resistance, maintain strength at elevated temperatures, and stability in extreme environments. The study focused on creating MoZrB2 composites using a thermal spray coating technique, varying the parameters of spraying distance, number of passes, and gas pressure, and testing the resulting castings to evaluate their hardness and Young’s Modulus. The primary objective of the research was to use the Taguchi technique for identifying the optimal parameters for generating the highest Young’s Modulus and hardness for the castings. The Taguchi method integrates experimental and analytical principles to identify the most significant parameter affecting the response, which can significantly enhance overall performance. The study found that the optimal parameters were a spraying distance of 20 cm, gas pressure of 6 bar, and the number of passes of 18. The Taguchi method accurately predicted the parameters that produced the highest properties for the composite coatings, which demonstrated good surface formation without hot cracks and fewer pores, with well-formed metallurgical bonding between the coating and the substrate.
