| Popis: | The effects of kinds of secondary phases on texture and mechanical properties of Mg–Zn–Er alloys were investigated. The results suggest that the I-phase has a great effect on modification of the texture via the discontinuous dynamic recrystallization mechanism (DDRX), which tends to form well-developed equiaxed recrystallized grains. Meanwhile, the W-phase plays an important role in refining the grain size via continuous dynamic recrystallization (CDRX), companied with a higher maximum texture intensity. Thus, the Mg–6Zn–1Er alloy containing I-phase shows a performance of higher elongation of 20.4%. The Mg–2Zn–2Er alloy including W-phase displays a better tensile strength, and the yield strength (YS) is about 247 MPa. |
