Increase in grain size during recrystallization of heat resistant nickel alloys

Conclusions

We have shown that the critical increase in grain size during recrystallization occurs only when recrystallization proceeds during plastic deformation or during the cooling of the alloy after plastic deformation or under certain conditions (heating rate) during repeated heating. If recrystallization does not occur during plastic deformation (cold deformation) and the rate of repeated heating is such that polygonization processes have time to occur then there is no critical increase in the grain size.
