Yes, quenching with water can lead to metallurgical implications. The material cools too quickly causing phase changes in the HAZ and grain boundaries.Ive read that quenching a weld with water is a no no as it results in a brittle work hardened joint.
I dont suppose there is any difference quenching with an air blow gun is there?
Mild steel doesn't have enough carbon in it to be hardened or tempered so will react to quenching very differently from med carbon steels or alloy steels

Chucking water over the part when you've finished welding won't but flame straightening (or bending, heat shrinking etc) works on pretty much any weldable* metal. Obviously material properties (thermal conductivity, co-efficient of expansion etc) effect technique etc, how well it works and how serious any metallurgical side effects areI'm thinking no, but could any of the above be used to straighten aluminium extrusions? SHS etc
