The simulation of nitrogen quenching of a crosssection of 100 x 100 mm2 clarifies:
1.Edge transforms completely martensitic asdesired,
Core passes through the temperaturerange of pre-eutectoid carbide precipitationand already partially transforms to bainite
The simulation of nitrogen quenching of across-section of 400 x 400 mm2 clarifies:
1.Eage transforms almost completelymartensitic, but aready low bainite content
2.Core passes through temperature range ofpearlitic transformation and already partiallytransforms into painite.
