A356 合金的半固体泥浆被准备由低过热流并且稍微电磁激动人心,在哪个纯铜杆被用来生产本地人寒心。效果由形态学和尺寸上的杆寒心主要(艾尔) 在 A356 被研究。结果显示由杆寒心显著地影响形态学和尺寸主要(艾尔) 。主要(艾尔) 在 A356 一致地与像粒子的形状被散布,并且在结构形态学没有短暂区域。与没有本地人,准备的样品相比寒心,成核率,形态学和谷物尺寸主要(艾尔) 在 A356 准备了由低过热流并且稍微电磁与杆激动人心显著地被改进。在条件下面寒心,流的温度能合适被提起获得主要(艾尔) 与像粒子的形状。
The semi-solid slurry ofA356 alloy was prepared by low superheat pouring and slightly electromagnetic stirring, in which a pure copper rod was used to produce local chilling. The effect of chilling by the rod on morphology and size of primary a(Al) in A356 was researched. The results indicate that the chilling by the rod remarkably affects the morphology and the size of primary a(Al). Primary a(Al) with particle-like shape is distributed uniformly in A356, and there is no transient area in structure morphology. Compared with the samples prepared without the local chilling, the nucleation rate, morphology and grain size of primary a(Al) in A356 prepared by low superheat pouring and slightly electromagnetic stirring with the rod are markedly improved. Under the condition of chilling, the pouring temperature can be suitably raised to obtain primary a(Al) with particle-like shape.
