Does water quenching a boolit increase
the outer hardness only
the entire hardness equally
the outer hardness with less hardness increase as you move inward towards the center of the boolit
I believe the answer may be #3 since the outside of the boolit would see the greatest speed of cooling and thus benefit the most from the hardening process. The center would cool faster than air cooled, but not as fast as the outside of the boolit that is in contact with the water.
Perhaps someone can explain the metallurgy behind hardness increase with water quenching boolits.
If the answer is #3, has anyone ever water dropped a cast boolit to increase hardness...and then cut the boolit in half and measured hardness from the edge towards the center in 0.1" incraments? (I'm an engineer and I like data !)
