Challenging Ultra Grain Refinement of Ferrite in Low-C Steel Only by Heat Treatment

It is well-known that grain refinement is one of the most effective ways to improve strength of metals without addition of alloying elements. In order to obtain bulky metals having ultrafine grained (UFG) microstructures with average grain sizes smaller than 1 μm, severe plastic deformation (SPD) pr...
