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.

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.

The formation of amorphous porous bodies and in particular to a method of manufacturing such bodies from amorphous particulate materials. The method allows for the control of the volume fraction as well as the spatial and size distribution of gas-formed pores by control of the size distribution of the powder particulates. The method allows for the production of precursors of unlimited size, and because the softened state of the amorphous metals used in the method possesses visco-plastic properties, higher plastic deformations can be attained during consolidation as well as during expansion.

Production of amorphous metallic foam by powder consolidation

An article comprising a bulk metallic glass skin having one or more functional features integrated therein is described and a method of forming the same is described. The one or more functional features exhibit a variation in stiffness between the one or more functional features and the bulk metallic glass skin that is defined by an applied force over an achieved deformation. The stiffness of each of the one or more functional features is at least 1000 times less than an average stiffness of the bulk metallic glass skin.

Multi step processing method for the fabrication of complex articles made of metallic glasses

A very low pressure gas or blow forming process for shaping a bulk metallic glass (BMG) in its supercooled liquid state that avoids the frictional stick forces experienced by conventional shaping techniques by engineering the expansion of a pre-shape or parison of BMG material such that substantially all of the lateral strain required to form the final article is accomplished prior to the outer surface of the parison contacting the surface of the shaping apparatus is provided. The capability offered by the inventive shaping process to avoid the frictional forces exerted by the shaping apparatus surface allows for the formation of precision net-shape complex multi-scale parts and components using processing conditions inaccessible by conventional processes.

Method of blow molding a bulk metallic glass

A method of joining a bulk metallic glass to a second similar or dissimilar material in an air environment. The method includes the steps of: a) removing an oxide layer on at least a portion of a surface of a first bulk metallic glass during thermoplastic forming of the first bulk metallic glass in a supercooled liquid region, wherein the removing of the oxide layer on the at least the portion of the surface creates a fresh surface that is at least substantially free of oxides and/or contaminants; and b) joining the fresh surface of the first bulk metallic glass to a second material.

A method of processing BMGs in a non-ideal environment (such as air) to create a uniform and smooth surface is provided. By utilizing the contact-line movement and an engineered flow pattern during TPF the method is able to create complex BMG parts that exhibit uniform smooth appearance or even can be atomically smooth. In addition, to mending surface imperfections, this method also eliminates void formation inside the material, allows for the creation of precise patterns of homogeneous appearance, and forms improved mechanical locks between different materials and a BMG.

Method and system based on thermoplastic forming to fabricate high surface quality metallic glass articles

A class of materials has advantageous utility in electrocatalytic applications, e.g., fuel cells. The materials circumvent conventional Pt-based anode poisoning and the agglomeration/dissolution of supported catalysts during long-term operation by exploiting the unique physical and chemical properties of bulk metallic glass to create nanowires for electrocatalytic applications, e.g., fuel cell and battery applications. These amorphous metals can achieve unusual geometries and shapes along multiple length scales. The absence of crystallites, grain boundaries and dislocations in the amorphous structure of bulk metallic glasses results in a homogeneous and isotropic material down to the atomic scale, which displays very high strength, hardness, elastic strain limit and corrosion resistance. The melting temperatures of the disclosed bulk metallic glasses are much lower than the estimated melting temperatures based on interpolation of the alloy constituents making them attractive as highly malleable materials.
