Method of Making Nanocrystalline Metal Flakes via Ultrasonic Shot Peening
- Summary
- Researchers at Purdue University have developed a method to generate NC metal flakes by ultrasonic shot peening (USP). This technology leads to the formation of nanosized grains in the metal flakes, which has the potential for application in the field of polymer composites and surface coating. This method is highly efficient and environmentally friendly because the mechanism of this method is the severe plastic deformation and fatigue behavior of the materials.

- *Background
- Due to its peculiar and interesting mechanical, physical, and chemical properties, such as increased mechanical strength, enhanced diffusivity, and higher specific heat, nanocrystalline (NC) materials are experiencing rapid development. As opposed to conventional coarse-grained metal flakes, NC materials have a wide variety of technical applications such as electronics, catalysis, batteries, ceramics, magnetic data storage, structural components, etc. The industry needs a method to more rapidly and efficiently produce NC materials.
