Metallic glasses are noncrystalline solid metals that have high strength, excellent corrosion resistance, and impressive hardness compared to their crystalline counterparts. A modern understanding of how glasses are formed along with an appreciation for the high ultimate yield strength of metallic glasses are leading to a boon in applications for these unique materials.

The high heating and cooling rates of additive manufacturing make it a good fit for metallic glasses, whose high elasticity, strength, hardness, and corrosion resistance are used in high-performance applications such as aerospace, defense, and biomedical devices.

Ultrasonic additive manufacturing (UAM) originated from ultrasonic metal welding, first developed in the 1950s. Modern applications include welding of battery tabs, thin foil packaging, and electronic wire production. The article reports on a unique UAM method that excels at mixed metal applications. The technology won the 2022 ASM Engineering Materials Achievement Award.

Throughout its 100-year history, the Materials and Manufacturing Directorate has conducted groundbreaking critical research programs responsible for a multitude of technological advances. This article summarizes just a few of the significant achievements of the directorate during its history.

A new fusion cladding process that uses high-intensity arc lamps can produce pinhole free, smooth, uniform coatings as thick as 15 mm from various feedstock materials. This article briefly describes the process and the corrosion, wear, and high-temperature behavior of fusion claddings designed for oil and gas pipelines and related components.

Aerosol deposition offers an alternative to conventional thin film processes when mesoscale coatings are needed. The process is being used to create readily integrated, high density ceramic and metallic thick films on a variety of substrates at room temperature.
