- Abstract
The effect of hot deformation and chemical composition on the microstructure and hardness of experimental grades of low-carbon and ultralow-carbon C-Mn-Mo-Nb-B steels is studied by the method of physical simulation. It is shown that deformation of austenite at a temperature below that of recrystallization leads to formation of polygonal ferrite and high-temperature ferrite with bainitic morphology. The effect is the most pronounced in boron-bearing steels. Simultaneous alloying with Mo, Nb, and B seems to be the most effective for ensuring high hardness.
