摘要： A mould for casting a component in a directional solidification casting process having a preferred direction of grain growth (non-axial ) comprises a shell defining a cavity for receiving molten material. The cavity defines a three dimensional shape made up of a finished component geometry portion (42, 43, 44) and a sacrificial geometry portion (45) wherein the sacrificial geometry portion (45) includes a notch (48) which is shaped and positioned so as to, in use, contain high angle grain boundaries between dendritic growth in the preferred direction (non-axial ) and dendritic growth in a competing direction to the preferred direction (axial ) within the sacrificial geometry portion of a casting solidifying in the mould.

摘要： A method for making an equiaxed investment casting. The method utilizes an ultrasonic generator to send an ultrasonic pulse into molten metal in an investment casting mold. The investment casting mold is positioned within a working zone of furnace having low output induction coils for generating a convection current in molten metal. The ultrasonic pulse separates dendrites growing from the face of the mold inward into the molten metal. Instead, equiaxed grains can nucleate within the molten metal. In addition, the ultrasonic pulse and the low output induction coils circulate the molten metal as solute is rejected from solidifying equiaxed grains. The mixing reduces the effects of segregation in the solidifying alloy and assists in nucleating equiaxed grains.
摘要翻译： 制造等轴熔模铸造的方法。 该方法利用超声波发生器在熔模铸造模具中将超声脉冲发送到熔融金属中。 熔模铸造模具位于具有低输出感应线圈的炉的工作区域中，用于在熔融金属中产生对流。 超声波脉冲将从模具表面向内生长的树枝分离成熔融金属。 相反，等轴晶粒可以在熔融金属内成核。 此外，超声脉冲和低输出感应线圈使熔融金属循环，因为溶质被凝固等轴晶粒排斥。 混合减少了固化合金中的偏析效应，有助于成核等轴晶粒。

摘要： An aluminum alloy and a method of casting. At least one of zirconium, scandium, a nucleating agent selected from the group consisting of metal carbides, aluminides and borides, and rare earth elements are added to the alloy while in the molten state such that upon solidification, the cast alloy exhibits improved hot tear resistance. In a particular form, the nucleating agent may be titanium diboride for grain refining. Other agents that can be used for grain refining include scandium, zirconium, silicon, silver and one or more rare earth elements. In the case of rare earth elements, mischmetal may be used as a precursor. Combinations of titanium diboride and at least one other agent are especially effective in reducing the incidence of hot tearing in products cast from the modified aluminum alloy.
