Abstract: Flexible BMG elements and methods for making the flexible BMG elements. The BMG element contains a main body made from a BMG material and may further contain a flange. The main body may contain at least one opening. The main body may be a thin-walled structure that is compressible, extendable, and/or bendable. A surface of the main body may be corrugated with a series of ridges and furrows.

Abstract: The present invention relates to bulk metallic glass (BMG) structures used for hydrogen applications such as hydrogen infrastructure and vehicle applications. The BMG structure may include a main body with at least one opening, wherein the main body is made from a BMG material. The BMG structure may be configured to receive, store, transport and/or dispense hydrogen fuel in a form of fluid including one of gas, liquid, compressed gas or liquid, cryo-compressed hydrogen, and a combination thereof. The BMG structure may be configured to be under a direct exposure to hydrogen, wherein hydrogen is on the internal surface of the structure and is not on the exterior of the structure during operation.

Abstract: A pressure vessel containing a main body with at least one opening. The pressure vessel is made from a BMG material. The pressure vessel may contain an additional part such as a neck, a liner, a rib, a lattice, a fin, and a diaphragm. The pressure vessel may be free of a welded joint in entirety. The pressure vessel may contain multiple parts in the main body, each of which is free of a welded joint. The pressure vessel may be made through thermoplastic forming.

Abstract: This invention describes a method and hardware of how to deform metallic glasses under low force and stabilized conditions to fabricate thin and large area metallic glass sheets. It is based on a combination of thermoplastic rolling and stretching and typically combined with a pre-heating method. The predominant mode of deformation is dependent on the BMG conditions such as thickness, viscosity, and crystallization time.

Abstract: A reusable mold comprising a flexible bulk metallic glass mold insert comprising one or more mold cavities removably coupled to a support mold and a method of making the reusable mold. The support mold is removable from the flexible bulk metallic glass mold insert without macroscopic elastic flexing or deforming of the support mold. The reusable mold may be used for molding one or more bulk metallic glass parts and the one or more molded bulk metallic glass parts may be released from the flexible bulk metallic glass mold insert by elastically flexing the flexible mold insert.
