The tests were performed in the temperature range 850-1150 °C and strain-rate range 0.001-10 ssup{-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 molsup{-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 ssup{-1}"},{"@xml:lang":"sl","#text":"Raziskana je bila vroča preoblikovalnost orodnega jekla za delo v hladnem 95MnWCr5.
