When were they invented?

In 1960, Pol Duwez and his group at the California Institute of Technology reported the first Au-Si liquid-metal alloy to be vitrified by cooling from the molten state. These metallic alloys require cooling rates of 1,000,000 degrees per second to suppress crystallization and form a metallic glass, thereby restricting the specimen geometry to micron-thin sections. 

How are they formed?

Unlike conventional glasses (e.g. silicate glasses), metallic glasses cannot be found in nature as they cannot evolve by a natural process. They are frozen metallic liquids lacking crystallinity, and can only be processed in the laboratory. Amorphous configurations are retained in the solid state by cooling from the melt with sufficient celerity so as to prevent formation of the equilibrium crystalline structures.

What are the benefits?

Metallic glasses are emerging as a class of materials with unique and unusual properties that make them candidates for many structural applications.

These properties include near theoretical strengths and high hardness combined with high formability, low damping, large elastic strain limits, and the ability to be thermoplastically formed into precision net shape parts in complex geometries, all of which are superior to corresponding crystalline metals and alloys.

"GlassiNickel alloys are 2 to 3 times stronger and harder than high strength Steel and Titanium alloys."

- Bill Johnson, Glassimetal Technology

Compared to their crystalline counterparts, the exceptional properties of metallic glasses enable the design of components with smaller footprints, greater complexity, and enhanced precision and tolerance. 

What are the notable recent developments?

For the past 30 years, it has been known that metallic glasses can be directly made in bulk form by solidifying the melt at relatively low cooling rates. In the early 1990's, William L. Johnson and his group at the California Institute of Technology developed Zr-based bulk metallic glasses (BMGs), and in particular the Zr-Ti-Ni-Cu-Be system,  that present a low cooling rate of about 1 degree per second allowing casting of large ingots with thicknesses up to 10cm.

Shortly after, the first commercial Zr-based BMG was commercialized and is in use today in several commercial applications due to its unique engineering characteristics. 

The Zr-based BMGs are deemed rather "exotic" due to raw material and processing costs exceeding those for mainstream metals such as steel and aluminum. Recently, new ferrous-metal glasses based on Iron and Nickel bearing Chromium have been developed with material and cost structures similar to those for mainstream engineering alloys. Precious metal BMGs made of Platinum, Palladium, and Gold have also been recently introduced intended for use in hallmarked jewelry applications.

What's is the next frontier?

We want to expand the boundaries of metal performance and manufacture of metallic parts. The combination of exceptional materials (Metallic Glasses) and a pioneering processing platform (Rapid Discharge Forming) offers major advantages over conventional metals processing methods such as die-casting, metal powder injection molding, machining... With cycle times on the order of seconds, near net shaping, an environmentally friendly process, high precision, and superior material performance, our technology redefines the cost vs. performance tradeoff achievable for metallic components.
