      abstract     = {Two MnCr stainless steels (0.17C-10Mn-18Cr-xSi-1V-0.25N,
                      $wt.\%)$ with varying Si contents (x=0.4 and 2.2 wt. $\%)$
                      were designed with a stacking fault energy of 35 mJ/m2 to
                      activate the TWIP effect. The high-temperature deformation
                      behavior and room-temperature (RT) tensile properties were
                      investigated to explore the impact of Si in both high and RT
                      regimes. The high-temperature behavior of the steels was
                      assessed using hot-rolled plates through compression tests
                      at temperatures ranging from 950 to 1100 ◦C and strain
                      rates from 0.01 to 10 s􀀀 1. Hot deformation processing
                      maps were established to identify the safe and unstable
                      deformation zones. The RT tensile properties were evaluated
                      through uniaxial tensile tests of fast-heating (FH) annealed
                      cold-rolled sheets at temperatures ranging from 800 to 1200
                      ◦C for 3 min. Microstructural analysis of the hot-rolled
                      and FH annealed structures was conducted using electron
                      backscatter diffraction and laser scanning confocal
                      microscopy, and precipitation was characterized by
                      transmission electron microscopy. The findings demonstrated
                      that MnCr-V steel with higher Si content (2.2 $wt.\%)$ had
                      reduced hot-deformation resistance and lower activation
                      energy for deformation (477 kJ/mol) compared to its lower Si
                      counterpart (507 kJ/mol). This can be attributed to the soft
                      ferrite phase within the austenite during elevated
                      temperature tests. Conversely, the RT tensile properties
                      exhibited an opposite trend, with the high Si steel showing
                      increased yield strength (YS) and Ultimate tensile strength
                      (UTS) compared to the low Si steel. This improvement is due
                      to solid solution strengthening from Si, precipitation
                      strengthening from V(C,N) particles, and a fine-grained
                      recrystallized structure resulting from short annealing. For
                      instance, after a FH process at 1000 ◦C for 3 min, the YS,
                      UTS, and total elongation values were 665 MPa, 980 MPa, and
                      40 $\%,$ respectively, for the low Si steel, while the high
                      Si steel achieved values of 715 MPa, 1045 MPa, and 30 $\%,$
                      respectively. Mechanical twinning was evident in both
                      materials.},
