Processes, microstructure and properties of vanadium microalloyed steels [PDF]

, 2009
Vanadium as an important alloying element in steels was initially associated with the properties achieved following tempering. Interest in the microstructure was stimulated by the advent of transmission electron microscopes with a resolution of ~1nm ...
