Reverse Hall–Petch Effect of Nano-Bainite in a High-Carbon Silicon-Containing Steel

Metals
High-strength steels are widely used in various mechanical production and construction industries for their low cost, high strength and high toughness. Among these, bainitic steels have better comprehensive performance relative to martensite and ferrite.

Further evidence of tetragonality in bainitic ferrite [PDF]

, 2014
There is growing evidence that bainitic ferrite which retains a substantial amount of carbon in solid solution does not have cubic symmetry. We provide additional data on a different nanostructured bainitic steel to support this evidence, based on ...
