A high strength and toughness Zn-Mg-Mn alloy with ultimate tensile strength of 358 MPa and fracture elongation of 23.5% was successfully prepared by 12-pass equal channel angular pressing. The multi-interactions between dislocations and refined microsturcture including grain boundaries, eutectic structure, MnZn₁₃ particles and dislocation arrays contributed to strengthening of the alloy.

高强度和韧性的Zn-Mg-Mn合金中位错的多重相互作用和精细的微观结构

通过12道次等通道角挤压成功制备了高强度和韧性的Zn-Mg-Mn合金，极限抗拉强度为358 MPa，断裂伸长率为23.5％。位错与精细组织（包括晶界，共晶组织，MnZn ₁₃颗粒和位错阵列）之间的多重相互作用有助于合金的强化。
