      abstract     = {A new ultrahigh-strength structure is created by severe
                      plastic deformation of a martensitic $0.1 wt.-\%$ C steel
                      using high pressure torsion (HPT) at room temperature.
                      Tensile tests reveal an ultimate tensile strength of
                      2.4 ± 0.1 GPa after an equivalent strain of
                      $ε_{vM}$ = 7.5 – to our knowledge the highest tensile
                      strength ever reported for a carbon steel with such low
                      carbon content. During HPT, a lamellar microstructure is
                      formed with decreasing lamellar spacing for increasing
                      plastic strain. Micropillar compression tests give crucial
                      insights into the mechanical properties, which are
                      correlated to the deformation behavior of this material.
                      Strong similarities compared to HPT-treated pearlitic steel
                      are found in spite of the large differences concerning both
                      carbon content and phase composition. The possibilities and
                      limits of strength maximization in carbon steels are
                      evaluated and discussed.},
