Various embodiments provide apparatus and methods for melting materials and for containing the molten materials within melt zone during melting. Exemplary apparatus may include a vessel configured to receive a material for melting therein; a load induction coil positioned adjacent to the vessel to melt the material therein; and a containment induction coil positioned in line with the load induction coil. The material in the vessel can be heated by operating the load induction coil at a first RF frequency to form a molten material. The containment induction coil can be operated at a second RF frequency to contain the molten material within the load induction coil. Once the desired temperature is achieved and maintained for the molten material, operation of the containment induction coil can be stopped and the molten material can be ejected from the vessel into a mold through an ejection path.

Inline melt control via RF power

Provided in one embodiment is a method of forming a connection mechanism in or on a bulk-solidifying amorphous alloy by casting in or on, or forming with the bulk-solidifying amorphous alloy, a machinable metal. The connection mechanism can be formed by machining the machinable metal.

Insert casting or tack welding of machinable metal in bulk amorphous alloy part and post machining the machinable metal insert

Methods and apparatus for creating an integral assembly formed from a transparent member and a housing formed at least in part of a bulk-solidifying amorphous alloy. The methods and systems create integral transparent member and amorphous metal alloy-containing parts using thermoplastic molding techniques in which the amorphous metal is molded to the transparent member in a thermoplastic, not liquid, state.

Methods and systems for forming a glass insert in an amorphous metal alloy bezel

Provided in one embodiment is a method of making use of foams as a processing aid or to improve the properties of bulk-solidifying amorphous alloy materials. Other embodiments include the bulk-solidifying amorphous alloy/foam composite materials made in accordance with the methods.

Insert molding of bulk amorphous alloy into open cell foam

Provided in one embodiment is a method of selective microstructural transformation, comprising: providing a part comprising a bulk amorphous alloy; heating selectively a portion of the part to a first temperature such that at least some of the portion is transformed into a crystalline phase; and processing the transformed portion.

Selective crystallization of bulk amorphous alloy

Pressure sensing systems comprising bulk-solidifying amorphous alloys and pressure-sensitive switches containing bulk-solidifying amorphous alloys. The bulk-solidifying amorphous alloys are capable of repeated deformation upon application of pressure, and change their electrical resistivity upon deformation, thereby enabling measurement of the change in resistivity and consequently, measuring the deformation and amount of pressure applied.

Bulk amorphous alloy pressure sensor

Various embodiments provide materials, parts, and methods useful for electronic devices. One embodiment includes providing a coating on at least one surface of a substrate, increasing an amorphicity of the coating, and incorporating the substrate including the coating having increased amorphicity into an electronic device. Another embodiment relates to frictionally transforming a coating from crystalline into amorphous to form a metamorphically transformed coating for an electronic device. Another embodiment relates to an electronic device part having a metamorphically transformed coating disposed on at least one surface thereof.

Consumer electronics machined housing using coating that exhibit metamorphic transformation

The embodiments described herein relate to BMG articles with high bulk having all dimensions greater than the critical dimension. Exemplary BMG article can include at least one bulk component and/or one or more fixation elements configured on surface of the bulk component or inserted into the bulk component. Other embodiments relate to methods of making the BMG articles by thermo-plastic-formation of BMG alloy materials.

BMG parts having greater than critical casting thickness and method for making the same

Exemplary embodiments described herein relate to methods and apparatus for forming a coating layer at least partially on surface of a BMG article formed of bulk solidifying amorphous alloys. In embodiments, the coating layer may be formed in situ during formation of a BMG article and/or post formation of a BMG article. The coating layer may provide the BMG article with surface hardness, wear resistance, surface activity, corrosion resistance, etc.

Coating of bulk metallic glass (BMG) articles

Various embodiments provide methods and apparatus for forming bulk metallic glass (BMG) articles using a mold having a stationary mold part and a movable mold part paired to form a mold cavity. A molten material can be injected to fill the mold cavity. The molten material can then be cooled into a BMG article at a desired cooling rate. While injecting and/or cooling the molten material, the movement of the movable mold part can be controlled, such that a thermal contact between the molten material and the mold can be maintained. BMG articles can be formed without forming an underfilled part. Additional structural features can be imparted in the BMG article during formation. At least a portion of the formed BMG article can have an aspect ratio (first dimension/second dimension) of at least 10 or less than 0.1.

Injection compression molding of amorphous alloys

Provided in one embodiment is a method of forming a movable joint or connection between parts that move with respect to one another, wherein at least one part is at least partially enclosed by at least one second part. The method includes positioning an etchable material over an at least one first part, molding or forming an at least one second part over at least the etchable material, and removing the etchable material.

Movable joint through insert

An injection molding system and methods for improving performance of the same. The system includes a plunger rod and a melt zone that are provided in-line and on a vertical axis. The plunger rod is moved in a vertical direction through the melt zone to move molten material into a mold. The injection molding system can perform the melting and molding processes under a vacuum. Skull formation in molten material is reduced by providing an RF transparent sleeve in the melt zone and/or a skull trapping portion adjacent an inlet of the mold. It can also be controlled based on the melting unit. Vacuum evacuation can be reduced during part ejection by using a plunger seal, so that evacuation time between cycles is reduced.

Provided in an embodiment is a method for molding, including: providing a molten alloy in a space between a mold cavity and an etchable block shaped to form an undercut on a part formed in the space, cooling the molten alloy to form the part with the undercut, and etching the etchable block. An undercut is a beveled edge caused by an etchant attacking an etchable block laterally and optionally vertically. The formed part can be made of a bulk amorphous alloy. In some cases, the etchable block can also be used to form at least one threaded portion in the part.
