摘要: Abstract The microstructural evolution, texture and mechanical properties of nine Mg-4Zn-xCa-yMn alloys (x = 0.3, 0.6, 1.0; y = 0.2, 0.3, 0.7 wt.%) were investigated systematically. Alloying with Ca Mn refined the grains extruded sheets increased unDRX fraction. could be heterogeneous nucleation site Ca2Mg6Zn3 phase because a good atom matching at orientation relationship ( 2 ¯ 1 ) Mn//(1 11)Ca2Mg6Zn3, 〈 5 〉 Mn//〈1103〉Ca2Mg6Zn3. traditional weakening effect was strongly decreased for simultaneously addition Mn. With increasing concentration, strength ductility decreased. Mg-4Zn-0.6Ca-0.7Mn exhibited combination ultimate tensile (320 MPa), yield (286 MPa) elongation (16%). A model strengthening indicated that grain boundary precipitate made large contribution to Mg-4Zn-0.6Ca-0.7Mn. In addition, dynamic recrystallization, modification from different parts also have been analyzed in detail.
