摘要

Two heats of Indian reduced activation ferritic / martensitic steel have been produced with similar chemical composition and identical process parameters except the start and final rolling temperature referred as P950 and P1050, respectively. Fracture behaviours of both the heats have been evaluated, and it was found that quasistatic fracture properties are better for P1050 than P950. An attempt is made to establish the reasons for the observed behaviour through optical, scanning electron microscopic, electron backscatter diffraction and transmission electron microscopic studies. These variations are attributed to the difference in rolling temperature of both heats. P1050 meets the acceptance criteria as per Indian specifications, and it compares favourably with the international grades of equivalent RAFM steels.
