Eutectoid Steels with no V and V

Steel name: Eutectoid steels with no V and V
Diagram No.: 7863
Type of diagram: CCT
Chemical composition in weight %: Eutectoid steel
Steel group: Carbon steels
Note: Austenitizing temperature: 1100 C, holding time: 5 min. CCT diagrams for eutectoid steels containing (a) no V and 50 ppm N, and (b) 0.072 wt pct V and 110 ppm N. The arrow shown in part (b) shows the direction of CCT shift with the addition of V and N. Both alloys contained 0.50 wt pct Si. [Brownrigg, 2002]. For eutectoid steels with a consistent austenite grain size, Brownrigg and Prior showed that adding 0.068 wt pct V and 60 ppm N shifted the CCT curves to higher temperatures and shorter times.
