Conclusions
-
1.
Below 950°, arsenic has little effect on the tendency to austenite grain growth, but the effect increases considerably at higher temperatures. This should be taken into account in selecting the heat treatment.
-
2.
Alloying of steel 16G2S with vanadium lowers the tendency to austenite grain growth in the temperature range investigated due to the inhibition of boundary movements by dispersed precipitates.
-
3.
Arsenic lowers the activation energy of austenite grain boundary migration, and also the surface energy of the grain boundaries.
