This invention is directed to mechanical and electromagnetic shielding features of an electronic device case. An electronic device case is formed of two housings, each housing having integrated snaps, channels, or other retaining features used to secure the housings together. The housings additionally include integrated retaining features used to secure electronic components within the device case. The housings and retaining features are formed of amorphous metals or other materials with high elasticities. Because the retaining features necessary to assemble the case and secure the electronic components to the case form integral parts of the housings, no external retaining features are required to assemble the electronic device in the case.

Sheet casting of metallic glasses and twin roll sheet casting of bulk metallic glasses and composite in an inert environment. Samples may be heated by RF to a temperature in the semi-solid region. After semi-solid processing, the partial liquid then may be poured or injected to achieve the desired shape. Plates of metallic glasses and/or metallic glass matrix composites may be formed (for example, through diecasting) and serve as a pre-form for rolling. In this configuration, the plates may be lowered through a radio frequency coil into compressing wheels, directly next to or below the coil. As the plates pass through the coil they may heat to above the glass transition temperature. Next, they may be fed into the rolling wheel to thermoplasically form the plates into thinner sheets.

Methods for casting a metallic material to form a component are described. The component can be a superalloy-containing turbine part, for example. The general method includes the step of pouring the metallic material, in molten form, into an investment mold; and then rapidly immersing the entire investment mold into a bath that contains a low-melting liquid coolant metal, so as to achieve substantially uniform, multi-directional heat transfer out of the molten material. The molten material that solidifies to form the component is characterized by a fine-grained, equiaxed grain structure. Related embodiments include the use of two ingots that constitute the superalloy material. One ingot includes the oxygen-reactive elements, and is prepared by a vacuum-melting technique. The other ingot includes the remainder of the elements, and can be prepared by a number of techniques, such as air-melting processes.

An annular hot preservation layer is disposed inside the peripheral cold mold plate. A cyclic clean crystalline region is formed between the peripheral cold mold plate and the annular hot preservation layer. A sacrificial crystalline region is formed inside the cyclic hot preservation layer. As the outer race of the annular clean crystallization zone contacts large area of the peripheral low cold mold plate, releasing heat rapidly, while the inner race contacts the annular hot preservation layer , heat dissipation is extremely slow, naturally result in forming orientational crystallization. The vast majority of impurities and segregations in the liquid metal are gathered at the portion contacting with the annular hot preservation layer, and thus after the liquid metal is solidified, the gathered impurities and segregations can be removed easily, to obtain a clean casting ingot. 1.
