The martensite phase essentially consists of a metastable iron phase oversaturated in carbon. Since the more carbon a steel has, the harder and more brittle it is, a martensitic steel is very hard and brittle. Because the cooling rate is so sudden, carbon does not have enough time for diffusion. Yes ,impact energy absorbing capacity will decrease..

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
