Parametry obróbki cieplnej stali narzędziowej w istotny sposób wpływają na jej strukturę, która z kolei kształtuje właściwości mechaniczne i eksploatacyjne, takie jak np.: twardość, udarność i odporność na zużycie ścierne. Pomimo licznych opracowań na ten temat brak jest w literaturze fachowej ścisłych zależności pomiędzy parametrami obróbki cieplnej stali narzędziowej a jej odpowiednimi właściwościami...
The assessment of the effect of tempering temperature on hardness and impact toughness of a 56NiCrMo7 grade hot work tool steel was presented in the paper. It has been found that the investigated steel, after quenching in oil from 800°C, softens quite slowly upon tempering within the range between 100 and 675°C, which was confirmed not only by hardness measurements but also by observed changes occurring...
