The characteristics of rapid solidification and microstructure formation of Fe-50wt%Sn hypermonotectic alloy heve been investigated. The rapid solidification microstructure is composed of regular arrays of fiber like β Sn phase, α Fe phase distributed in fiber interspacings, and a small amount of metallic compounds. The angle between the fiber array and ribbon surface is within the range of 0—15°. According to the heat transfer equation and Navier Stokes equation under melt-spinning condition, the solidification behaviors and microstructure formation processes are analyzed theoretically. It is revealed that the liquid phase flow has a remarkable effect on the phase separation of hypermonotectic alloy. This separation behavior occurs in the bottom of the melt puddle, which is about 200μm from roller surface, where the shapes of separated L 2 droplets are deformed by shear stress. The collision/stretch of the separated L 2 droplets finally leads to the formation of fiber like microstructures. Due to the high cooling rate, the peritectic transformation at elevated temperatures is suppressed, thus resulting in the existence of some metastable phase at room temperature.

The ribbons of melt-spun AZ91D magnesium alloy with thickness of 4070 μm and length of 80100 mm were obtained by a single roller apparatus. According to the grain morphology, the rapid solidification microstructure of melt-spun magnesium alloy is roughly subdivided into three crystal zones through the thickness section: the fine equiaxed zone near the roller surface, the inner columnar zone and the outer equiaxed zone near the free surface. The X-ray analysis results indicate that the microstructure of the alloy...

The ribbons of melt-spun AZ91D magnesium alloy with thickness of 4070 μm and length of 80100 mm were obtained by a single roller apparatus. According to the grain morphology, the rapid solidification microstructure of melt-spun magnesium alloy is roughly subdivided into three crystal zones through the thickness section: the fine equiaxed zone near the roller surface, the inner columnar zone and the outer equiaxed zone near the free surface. The X-ray analysis results indicate that the microstructure of the alloy is composed of the single phase α -Mg supersaturated solid solution and the eutectic reaction of L→α -Mg+β -Mg_(17)Al_(12) is suppressed due to rapid solidification. TEM analysis reveals that a little amount of β -Mg_(17)Al_(12) compound, which disperses inside the α -Mg grains and locates at the grain boundaries, is the product of precipitation from supersaturated α -Mg solid solution during cooling processes. Lots of dislocations and dislocation cells exist in α -Mg grains. With the increasing of roller velocity, the α -Mg grains become gradually finer and the inner columnar zone tends to elimination, and the density of dislocation inside the grains increases, and hence the strength and electrical resistivity of the alloy increase remarkably, while the elongation of the alloy decreases.

采用单辊实验技术研究了AZ91D镁合金的急冷快速凝固特征。合金条带的凝固组织沿厚度方向分为3个晶区:近辊面细晶区、内部柱状晶区和自由面等轴晶区。XRD分析表明,在快速凝固条件下,L→α Mg+β Mg17Al12的共晶反应受到抑制,条带凝固组织由过饱和的单相α Mg固溶体组成。TEM分析发现,α Mg晶内和晶界上离散分布着的少量Mg17Al12质点,系α Mg固溶体在连续冷却过程中脱溶析出的产物;α Mg中存在着大量的位错线和位错胞。随着辊速增大,晶粒更加细化,柱状晶区减小,位错密度增大,条带强度增加,塑性降低,电阻率增大。

The phase structure and dislocations in rapidly solidified AZ91D magnesium alloy were studied by TEM and XRD techniques. It shows that under rapid solidification conditions, the common eutectic transformation La-Mg+ Mg17Al12 in AZ91D alloys is suppressed to a great extent. As a consequence, the rapid solidification microstructures consist dominantly of supersaturated a-Mg solid solution, whose size is in the range of 0.8~6.0 m.

The phase structure and dislocations in rapidly solidified AZ91D magnesium alloy were studied by TEM and XRD techniques. It shows that under rapid solidification conditions, the common eutectic transformation La-Mg+ Mg17Al12 in AZ91D alloys is suppressed to a great extent. As a consequence, the rapid solidification microstructures consist dominantly of supersaturated a-Mg solid solution, whose size is in the range of 0.8~6.0 m. TEM analysis reveals that little amount of oval Mg17Al12 granules, trace polygonal Al8Mn5 particles and very small anomalistic -AlMg phase with the size of 5~70nm precipitate in a-Mg grains or their boundaries. The -AlMg phase is metastable transition configurations which is further transformed into stable Mg17Al12 phase. There are large numbers of dislocation pile-up and cells with the size of 0.2~0.7m in a-Mg grains, and the high dense dislocations mainly concentrate on the (002) close-packed face and exhibit a remarkable orientation.

采用TEM和XRD分析技术研究了快速凝固AZ91D镁合金的相结构及位错。实验发现,在急冷快速凝固条件下,AZ91D镁合金惯常发生的L-Mg+Mg17Al12共晶反应在很大程度上被抑制,形成了以过饱和的-Mg为主相的快速凝固组织。凝固组织由尺寸为0.8 m~6 靘的-Mg晶粒、离散分布于晶内和晶界上的尺度在5 nm~70 nm之间的少量的椭球形Mg17Al12和极少量的多角形Al8Mn5颗粒、以及弥散分布于晶内的非常细小的不规则形态-AlMg相组成。 -AlMg相为从-Mg晶内过饱和析出的、逐步向Mg17Al12相过渡的亚稳定组态。在-Mg晶粒内存在着大量的位错缠结和位错胞,位错胞尺寸在0.2 m~0.74 m之间;高密度位错主要存在于在-Mg 的(002)密排晶面上,且呈现出明显的方向性。
