Micrograph Library for Very Strong Bainite - Part 4

Francisca G. Caballero, Carlos Garcia Mateo and H. K. D. H. Bhadeshia

The first cheap bulk nanostructured alloy which can be produced in large quantities without capital investment, which can be formed and which can be produced without deformation or rapid heat treatment. The alloy can be made in large sizes (greater than 200 mm) in all directions. The controlling scale of the structure is the same as that of carbon nanotubes, and yet, it is stronger than any carbon nanotube for sizes in excess of 2 mm.

The particular steel examined here has the chemical composition Fe-0.80C-1.59Si-2.01Mn-0.24Mo-1Cr-1.51Co wt%.
