Anisotropy Cr-1Mo Steel Creep FEM Norton's Law Polycrystal Type IV Crack Welded Joint
Modified 9Cr-Mo steel is a candidate structural steel for demonstration fast breeder reactors (FBR's). Due to low thermal activatio n, the steel can maintain steady-state deformation during long-term creep. The creep strength of its weldment is lower than that of the base metal. Because of different creep strain rate in the solidified weld metal and heat-affected zone (HAZ), creep deformation in HAZ can be lowered but maximum principal stress augmented in fine-grained HAZ to cause detrimental Type IV crack...
