Effect of solid solution treatment on microstructure and mechanical properties of extruded MgY12Zn2,5 magnesium alloys
The microstructural evolution of MgY12Zn2,5 magnesium alloys was observed, and the strengthening and toughening mechanism of the alloys were studied. The results showed that the MgY12Zn2,5 alloy after solution treatment with higher content of 14H - LPSO (long - period stacking - ordered structures)...

| Summary: | The microstructural evolution of MgY12Zn2,5 magnesium alloys was observed, and the strengthening and toughening mechanism of the alloys were studied. The results showed that the MgY12Zn2,5 alloy after solution treatment with higher content of 14H - LPSO (long - period stacking - ordered structures) could more effectively inhibit the recrystallization and growth of recrystallized grains, and the microstructure was more fine and uniform. And its tensile strength (R<sub>m</sub>), yield strength (R<sub>v</sub>) were 395 MPa, 308 MPa and elongation (A) 17,5 %, respectively. In contrast, the MgY12Zn2,5 alloy treated at 470 °C for 24 h, whose Rm, Rv, were only 376 MPa, 282 MPa and A 15,5 %, respectively. |
