“…This is because the difference between the melting and boiling points of magnesium alloys is only 500 K, and when the energy density is too high, the magnesium element will evaporate. 21 As a result, the relative density obtained using the Archimedes drainage method exceeds 100%.…”

“…In the author's previous research, it has been proved that under the joint action of fine grain strengthening and precipitation strengthening, the compressive strength of the SLMed sample is significantly improved. 21 Figure 11 shows the surface morphology of the sample after compression fracture. It can be seen that the fracture morphology of the samples all presents river-like patterns and dissociation surfaces, which belong to brittle fracture.…”

“…This article is based on previous studies on the formability and pore defects of magnesium alloys. [20][21][22] The effect of SLM process parameters on the densification behaviour of magnesium alloys was investigated. The processing window of magnesium alloy is defined, the typical defect morphology distribution characteristics under different energy densities are revealed and the formation mechanism of defects is analysed.…”

In this study, Mg–Y–Sm–Zn–Zr samples were prepared using the selective laser melting technique. The influence of process parameters on the densification and mechanical properties of samples was systematically studied from a single-melt track to double melt tracks to block, and the formation mechanism of defects was analysed. Research results show that the appropriate laser power and scanning speed resulted in excellent single-melt path formability. When the scanning spacing was 80 μm, adjacent trajectories were closely connected without spheroidised particles and porosity defects. The densest samples were obtained at an energy density of 125 J/mm3 with maximum microhardness (86.8 ± 1.5 HV), and the compressive yield strength and ultimate strength reached 301.8 ± 5 MPa and 467.9 ± 5 MPa.

“…Identifying a novel material combination, such as zinc, aluminium, boron carbide, and molybdenum trioxide have propelled investigation into metal matrix composites. The main advantages of using Zr-Y-Zn-Al-Ti with Mg against the other matrix are higher strength, greater stiffness, less density, excellent high-temperature properties, enhanced wear characteristics and damping capabilities suggested by Wang et al [3]. Ali et al [4] recommended that magnesium alloy reinforced with particulates like RHA, FA, MoO3, and BA exhibits improved tensile strength, durability, and dry sliding wear behaviour.…”

In India, urban solid waste generation has risen over the last decade. The aspect of waste generation is a large amount of waste materials among all solid waste types. While using ash particles eliminates waste, it also contributes desirable qualities. In this research work, the effects of Himalayan nettle leaf ash (HNLA) bean pod ash (BPA) with molybdenum trioxide (MoO3) on the ZWK611 (Mg-Zn6.0-Y1.2-Zr0.2) alloy is examined. The as-cast alloy exhibits an α-Mg matrix, and cubic γ-phases are formed in addition to MoO3 particles. In this work, an attempt was made to choose a ZWK611 alloy reinforced with HNLA and BPA by varying weight percentages (X = 4, 8, 12, and 15%) with a constant weight percentage of MoO3 (5%) fabricated using spark plasma sintering (SPS) technique. The mechanical and physical properties were tested for both as-cast alloy and magnesium hybrid composites. Surface morphology and XRD are analysed to identify material behaviour. The addition of 12%(HNLA-BPA)/5%(MoO3) hybrid composite exhibits high strength as compared to the as-cast alloy.
