A transmission electron microscopy investigation of defects in an Mg-Cu-Mn-Zn-Y damping alloy

Microstructures and mechanical properties of high-strength Mg–Gd–Y–Zn–Zr alloy sheets processed by severe hot rolling

“…In recent years, because of the low density, high specific strength, high damping capacities and good casting properties, magnesium and its alloys have been received much attention as important structural materials, and they become the focus of worldwide interest as a candidate for lightweight components in automotive, electronic and space industries [1][2][3][4]. Among various magnesium alloys, rare earth (RE) containing alloys are known to show high strength, excellent creep resistance, good thermal stability, hence, much effort has been devoted to improve the mechanical properties of Mg-RE alloys [5][6][7][8][9][10].…”

Effect of long period stacking ordered (LPSO) structure on the damping capacities of Mg–Cu–Mn–Zn–Y alloys

“…2b) of the plate-like phase in the alloy 2, additional uniform spots in the Fig. 2c are readily observed between the direct spot and the (0 0 0 2) Mg spot in the [11][12][13][14][15][16][17][18][19][20] Mg pattern, which is characteristic of the 14H LPSO structure in the Mg-RE-Zn systems [24]. The phase compositions and regular pattern of secondary phases of the alloys are listed in the Table 2.…”

Microstructure and mechanical properties of rolled sheets of Mg–Gd–Y–Zn–Zr alloy: As-cast versus as-homogenized

“…Magnesium alloys containing rare earth (RE) elements have been attracting scientific interest for potential applications in transportation and aerospace industries for their exceptional precipitation strengthening response during isothermal aging process [1][2][3][4][5]. In order to extend the utilization of magnesium products, wrought processes were introduced to eliminate the porosities in casting and refine the microstructure resulting from the dynamic recrystallization (DRX) during plastic deformation.…”
