| 摘 要： | 采用金相显微镜(OM)、X射线衍射(XRD)研究了固溶处理对AM60B镁合金半固态组织的影响。结果表明,415℃固溶处理16h的AM60B镁合金锭料,经610℃部分重熔后可得到初生相颗粒细小、圆整、均匀的半固态组织。AM60B镁合金经415℃×16h固溶处理后,β-Mg17Al12相已完全溶解于α-Mg基体中。在610℃的等温热处理过程中,固溶阶段粗化的枝晶臂重熔,从而导致组织分离是形成这种组织的主要原因。

| Abstract: | Effects of solid solution treatment on semi-solid microstructure of AM60B magnesium alloy were investigated by OM (optical microscope), XRD (X-ray diffraction). The results show that semi-solid structure with fine and uniform spherical primary phase can be observed in AM60B magnesium alloy billets which were treated for 16 hours at 415℃ and then partially remelted at 610℃. The β-Mg17Al12 phase is completely dissolved in the α-Mg matrix with solid solution treatment for 16 hours at 415℃. Remelting of coarsened dendrite from solid solution treatment results in the separation of structure in the semi-solid alloy with isothermal treatment at 610℃, which is responsible for the formation of desirable semi-solid slurry structure. |
