DESCRIPTION:This is a story about a most elegant structure created in stee
 l\, consisting of crystals that are packed together so tightly that the bo
 undaries between them occupy a hundred million square metres in just a met
 re cube of the material.  This can be done in many ways\, but only one met
 hod has succeeded thus far in a concept that can be scaled to the producti
 on of thousands of tonnes or more of useful metal. And using a manufacturi
 ng technology that does not involve violent processing or thermal treatmen
 ts\; instead\, the structure evolves gently over a period of days at tempe
 ratures where food is normally cooked.\n\nThe method relies on a special c
 horeography of atoms\, where a crystal structure change is achieved withou
 t breaking any bonds. The resulting disciplined motion of atoms leads to e
 xceptionally fine product crystals that make the steel very strong\, and y
 et able to absorb energy on impact. The applications and  limitations of t
 his new material are described\, together with possible ways towards the d
 esign of a different concept that has the potential of creating an apparen
 tly impossible combination of properties.
