  • Hot workability of 95MnWCr5 tool steel = Vroča preoblikovalnost orodnega jekla 95MnWCr5
    Križaj, Ažbe, metalurg ...
    The hot workability of a 95MnWCr5 medium-alloyed cold-work tool steel was investigated with hot-compression tests on a Gleeble 1500D thermo-mechanical simulator. The tests were performed in the ... temperature range 850-1150 °C and strain-rate range 0.001-10 s[sup]{-1}. With decreasing of the deformation temperature and increasing of the strain-rate values of the peak strain, the peak and steady-state stresses increase. The hyperbolic sine Arrhenius function was used to determine the apparent activation energy for the hot workability. The apparent activation energy of 356 kJ mol[sup]{-1} for entire hot-working range was calculated using the peak stresses. The power-dissipation maps exhibited a single domain with the peak of efficiency in the range 30-40 %, the temperature range 960-1100 °C and a strain rate of 1.0 s[sup]{-1}.
