Subject: eucrystals

A science book that I have at home tells about some technology that can make 
materials gain their absolutely highest possible hardness, called no-dislocation 
crystals - those with not a slightest impurity, not a slightest crack, not a 
single disturbance to the crystalline network. According to that book, iron made 
that way is a thousand times stronger than regular iron. Are these crystals 
really ideal? How are they made? How much do they cost? Do they have any 
industrial perspectives, at least for sci fi?
