The obtained results indicated that the M7C3-carbides underwent intensive dissolution in austenite and were not detected above a temperature of 1100 °C. On the other hand, the MC-carbides remained almost completely unaffected and symptoms of dissolution were found only at a temperature of 1200 °C. The saturation of austenite by carbon, chromium and partly vanadium increased the hardness of the as-quenched material, with the maximum at an austenitizing temperature of 1025 °C"},{"@xml:lang":"sl","#text":"Vzorci ledeburitnega jekla Cr-V Vanadis 6 PM so bili avstenitizirani v temperaturnem območju 1000-1200 °C in kaljeni v olju.
