EFFECTS OF INCLUSIONS AND THEIR SURFACE CHEMISTRY ON CLEAVAGE FRACTURE IN A C-Mn STEEL WELD METAL
Tensile tests and fracture toughness tests supported by detailed fractographic examination have been carried-out on two sets of C-Mn weld metal samples with identical microstructure but different inclusion surface features.The tests showed that the tensile and fracture toughness properties were not significantly changed by the presence or absence of sulphide “patches” formed on inclusions.Analysis at a detailed level suggests that cleavage fracture initiated from inclusions with “sulphide” patches tends to be associated with higher fracture toughness than initiated from inclusions without “patches”.
