J. Adamczyk et al., INTERACTION OF CARBONITRIDES V(C,N) UNDISSOLVED IN AUSTENITE ON THE STRUCTURE AND MECHANICAL-PROPERTIES OF MICROALLOYED V-N STEELS, Journal of materials processing technology, 53(1-2), 1995, pp. 23-32
The effect of V(C,N) precipitates undissolved in austenite on structur
e and mechanical properties of the medium carbon microalloyed V-N stee
ls has been studied. The forgings have been produced in the process of
controlled plastic deformation by forging followed by accelerated coo
ling. It was shown that lowering austenitizing temperature and increas
ing amount of undissolved V(C,N) particles provided fine grain recryst
allized austenite structure after plastic deformation in the temperatu
re range of 1000-900 degrees C, and led to improvement of steel toughn
ess at low temperatures.
