Dear Friends,

Consider we have a mild-steel, cooling fast from welding temperature, we must have a fine grain structure with martensite formation.

Hypothetically, considering that we want to use this structure. I was wondering what is the relation between the impact energy and the structure? will it be decreased due to martensite formation? or increased due to fine grain? I understand that we don't use the martensite state of structures and we need to quench and tempering them.

Thanks,

Emad
