The range of accessible microstructures from the combination severe plastic deformation (SPD) and heat treatments a low carbon steel martensite under various processing conditions is evaluated. SPD results in temperature decrease for recrystallization austenitization upon subsequent annealing. On contrary, precipitation cementite takes place at higher temperatures after SPD. Whereas, certain thermal stability observed processing, even annealing have strong impact on simultaneous which differences dynamic static recovery. It shown that with each sequence unique can be produced to taken into account order produce material optimized tailored properties.
