New Way to Customize Metallic Grain Structures of Nanoparticles

Metallurgists have developed different methods to make a chunk of metal harder than before. They can twist it, bend it, pound it with a hammer, or send it between two rollers.

In these methods, the grain structure of the metal is broken up. Grain structure constitutes the microscopic crystalline domains forming a bulk piece of metal, where harder metals have smaller grains.
