Abstract:
Methods for creating sapphire windows are provided herein. In particular, one embodiment may take the form of a method of manufacturing sapphire windows. The method includes obtaining a polished sapphire wafer and applying decoration to the sapphire wafer. The method also includes cutting the sapphire wafer into discrete windows. In some embodiments, the cutting step comprises laser ablation of the sapphire.
Abstract:
One embodiment provides a method and apparatus for determining an unknown degree of crystallinity of a bulk-solidifying amorphous alloy specimen based on the heat capacity of the specimen. The method and apparatus make use of the different heat capacities of alloys having differing degrees of crystallinity.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
Disclosed herein are methods of combining at least one bulk-solidifying amorphous alloy and at least one additional metal or alloy of a metal to provide a composite preform. The composite preform then is heated to produce an alloy of the bulk-solidifying amorphous alloy and the at least one additional metal or alloy of the metal.
Abstract:
Disclosed is a method of controlling the production of a bulk-solidifying amorphous alloy by providing a set point control system, run in conjunction with a continuous smart feedback process control system that continuously monitors the processing conditions during manufacture, and continuously updates the smart feedback control system thereby enabling the control system to learn as the process is running.
Abstract:
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.
Abstract:
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.
Abstract:
Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.
