Aluminum wire scrap was collected to manufacture ingots, as we melted aluminum wires with high purity zinc and manganese metal. To examine the physical and mechanical properties, these alloys were cut into small strips and polished. The Vickers hardness (HV) technique was used to measure the hardness. The mechanical properties of the alloy increased with increasing zinc and manganese concentrations. It is observed that the values obtained from the EDX measurements and the SEM images are identical. Ingots contain gray and black areas; In the black region found, the elemental ratios of Al and Mn are high. XRD analyzes show that the α-Al peak is the main peak of all alloy configurations shown in all alloys. The secondary phases are Al2Mn and Al(MnZn) 6. It is clear that when the percentage of zinc increases, the parameters in the alloy structure decrease.

“…As shown in Figure 2d, some blocky dark compounds and high-density gray nanoscale particles disperse in the matrix. Previous studies indicate that these coarse compounds are Mg 2 Sn and MgSnY phases, and the nanoscale particles are the MgZn 2 phase precipitated during the aging process [16,18]. Figure 3 shows the stress-strain curves of as-aged ZMT614-1.0Y alloy tested at different temperatures.…”

“…At 300 • C, the fracture mechanism becomes solely the intergranular fracture type. Figure 8 shows the BSE images of fracture morphology of as-aged ZMT614-1.0Y alloy tested at 150 • C and 300 • C. The chemical compositions of Mg, Sn, and Y of the coarse particle in Figure 8a are 45.20%, 33.14%, and 10.13% (at.%), respectively, which are approved as Mg 2 Sn and MgSnY phases [16,21]. As shown in Figure 8a,b, a high density of twins and coarse Mg 2 Sn and MgSnY particles are distributed in the matrix.…”

The microstructures and high-temperature tensile properties of as-aged Mg-6Zn-1Mn-4Sn-(0.1, 0.5 and 1.0) Y (wt.%, ZMT614-Y) alloys were investigated by optical microscopy (OM), X-ray diffractometer (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high-temperature tensile tests. The tensile temperatures were 150 °C, 200 °C, 250 °C and 300 °C, respectively. The results showed that the phase compositions of as-aged alloys were α-Mg, α-Mn, MgZn2, Mg2Sn, and MgSnY phases. The Mg2Sn and MgSnY high-temperature phases inhibited grain growth in the heat treatment and tensile processes. The as-aged ZMT614-0.5Y alloy has the best high-temperature mechanical properties, with yield strength (YS), ultimate tensile strength (UTS), and elongation values of 277 MPa, 305 MPa, and 16.7%, respectively, at 150 °C. As the tensile temperature increased to 300 °C, the YS and UTS decreased to 136 MPa and 150 MPa, and elongation increased to 25.5%. The fracture mechanism changed as the tensile temperatures ranged from 150 °C to 300 °C, from the transgranular fracture type at temperatures of 150 °C and 200 °C, to the transgranular and intergranular mixed-mode fracture type when tensile temperatures increased to 250 °C, to an intergranular fracture mechanism at 300 °C.

“…Zn/Sn mass ratio can change the type of the Zn-rich and Sn-rich phases while micro-alloying elements can form new second phases [16][17][18][19][20][21][22][23][24][25][26][27]. Mg-Zn-Sn alloys with the Zn/Sn mass ratio of 1:1, and Mg-Sn-Zn-Mn alloys have excellent strength at elevated temperatures [28][29][30]. In Mg alloys containing Zn or Sn elements, such as Mg-Zn-Sn, Mg-Zn, and Mg-Sn alloys, the second phases usually include MgZn 2 , Mg 4 Zn 7 , Mg 2 Zn 11 , Mg 2 Sn, etc.…”

In this study, the microstructure of the Mg-4Zn-4Sn-1Mn-xAl (x = 0, 0.3 wt.%, denoted as ZTM441 and ZTM441-0.3Al) as-cast alloys was investigated using scanning electron microscopy (SEM), focused-ion/electron-beam (FIB) micromachining, transmission electron microscopy (TEM), and high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). The analysis results revealed that the microstructure of the ZTM441 and ZTM441-0.3Al as-cast alloys both mainly consist of the α-Mg matrix, skeleton-shaped MgZn2 eutectic texture, block-shaped Mg2Sn, and Zn/Sn-rich nanoscale precipitate bands along the grain boundary and the interdendrite. Nanoscale α-Mn dispersoids formed in the grain in the ZTM441 alloy, while no α-Mn formed in the ZTM441-0.3Al alloy instead of nanoscale Al3Mn2 particles. In the ZTM441 as-cast alloy, part of the Zn element is dissolved into the α-Mn phase, and part of the Mn element is dissolved into the MgZn2 phase, but in the ZTM441-0.3Al alloy, there are no such characteristics of mutual solubility. Zn and Mn elements are easy to combine in ZTM441 as-cast alloy, while Al and Mn are easy to combine in ZTM441-0.3Al as-cast alloy. The Mg-Zn phases have not only MgZn2-type crystal structure but also Mg4Zn7- and Mg149Zn-type crystal structure in the ZTM441-0.3Al as-cast alloy. The addition of Al changes the combination of Mn and Zn, promotes the formation of Al3Mn2, and the growth of the grain.
