Kaleidoscopic nanocomposite metals

A computer model of nanocomposite metals being cast. The pyramid shapes are called dendrites and show where the metal is solidifying. In the second half of the video the metal atoms attach to ceramic nanoparticles creating a kaleidoscopic effect known as grain refinement. These smaller ‘grains’ improve the quality and mechanical properties of the final metal. Exomet is finding ways of recreating this process on an industrial scale.
