摘要： An infiltration method of forming an article including providing a working mold including a solid binder member extending through an interior of the working mold, wherein the solid binder member is made of a binder material, and providing a layer of powder matrix material within a molding void of the working mold. The method further includes heating the working mold to form a molten binder pathway from the solid binder member to infiltrate the layer of powder matrix material.
摘要翻译：一种形成制品的浸渗方法，包括提供包括延伸穿过所述加工模具内部的固体粘合剂构件的加工模具，其中所述固体粘合剂构件由粘合剂材料制成，并且在模制空间内提供粉末基质材料层的工作模具。该方法还包括加热工作模具以形成来自固体粘合剂构件的熔融粘合剂路径以渗透粉末基质材料层。

摘要： A method for forming a drag bit (10) using displacements (16) having a rounded end (26) that creates a cutter pocket (13) having a rounded rear portion.(15). The displacement (16) may comprise an insert (46) on the rounded end that remains in the drag bit during and after formation. A cutter element (35) may then be attached to the upper portion of the insert (46). The rounded shape of the insert (46) provides a more even force distribution.
摘要翻译：一种使用具有圆形端（26）的位移（16）形成拖曳钻头（10）的方法，该圆形端（26）产生具有圆形后部的切割器凹口（13）。位移（16）可以包括在形成期间和之后保留在拖曳钻头中的圆形端部上的插入件（46）。然后可以将切割元件（35）附接到插入件（46）的上部。插入件（46）的圆形形状提供更均匀的力分布。

摘要： A system for casting comprising a mold for forming molten metal; a support for supporting the mold and transferring heat to and from the mold; and a furnace operable to substantially surround the mold through a preheat cycle, a heat cycle, and a cooling cycle. The furnace preferably moves vertically down to surround the mold for the preheat, heat, and cooling cycles and moves up and away from the mold after the cooling cycle is complete. In an alternative embodiment, the furnace may be replaced with a cooling can just before initiation of the cooling cycle. The support is preferably stationary and provides directional cooling for the mold during the cooling cycle.
摘要翻译：一种用于铸造的系统，包括用于形成熔融金属的模具; 用于支撑模具并将热量传递到模具的支撑件; 以及可操作以通过预热循环，热循环和冷却循环基本上围绕模具的炉。炉子优选垂直向下移动以围绕模具进行预热，加热和冷却循环，并在冷却循环完成之后向上和远离模具移动。在替代实施例中，炉子可以在冷却循环开始之前用冷却罐代替。支撑件优选是固定的并且在冷却循环期间为模具提供定向冷却。

摘要： Casing bits include a crown having a substantially hollow interior. The bit crown has blades over a face portion thereof, the blades including a plurality of cutting elements attached thereto. The bit crown further includes a composite inlay (85) positioned at least within the substantially hollow interior. Casing bits also include case hardened outer surfaces radially outside the drill-out region. Casing bits further include short- substrate cutting elements. Methods of forming a casing bit are also disclosed.
